An old man teaches his son when to speak, when to hold back, and what a word costs once it leaves.

Sit with me a moment. You have nowhere urgent to be and I have something to give you that nobody gave me until I was already halfway through ruining things with it.
I want to talk to you about your tongue.
You have two ears and one mouth, and there are people who will tell you this is an accident of the face. It is not. Everything about a person is a lesson if you read it properly, and the arrangement of your head is telling you the correct ratio. Listen twice as much as you speak, and you will be closer to right than most men ever get.
Begin with what a word actually is, because you have been treating them as free.
A word is a thing you make. It has weight. It goes out of your mouth and lands in another person’s body and lodges there, and it stays. Everyone alive is still carrying sentences that were said to them thirty years ago by people who have entirely forgotten saying them. You have some in you now. You know exactly what they are. Somebody said a thing to you once, perhaps in a bad temper, perhaps carelessly, and it went in and it made a shape in you, and that shape is still there. They meant nothing by it. It cost them a second. You have carried it half your life.
Understand, then, that you are doing this to people constantly.
I am a potter, so let me put it in the language I know best. When clay is wet it forgives you anything. Press it wrong and you can smooth it out. Ruin the whole form and you can crush it and begin again, and the clay holds nothing against you. The fire is where that ends. Once a piece has been through the heat, whatever is in it is in it forever, and no amount of water and no amount of regret will soften it back. A word is a thing that leaves your mouth already fired. There is no wet stage. The moment it is out, it is finished, and it has entered the world in its final form, and every apology you offer afterwards is a man kneeling beside something already hard, trying to press it with his thumbs.
That is why the wise have always been afraid of the tongue. Of every part of a man, it is the smallest and the least tiring to use, and it does more damage than his hands ever will. A man can destroy in nine seconds what he spent nine years building. There is a whole way of living built around this understanding, and the people who walk it treat speech the way a careful man treats fire in a dry season. They know what it can do. Their teachers made them hold their tongues for long stretches, months sometimes, before they were permitted to teach anything, because a man who has never governed his mouth has nothing worth hearing anyway.
Now. When to speak.
Speak when the thing you are about to say is true. This eliminates a great deal of what most men say in a day, and you will notice that immediately once you start applying it.
Speak when it is necessary. Truth alone is not enough, and this is where men who consider themselves honest do enormous harm. There are true things that need no saying. The true observation about a person’s face. The true fact about their failure, delivered on the day of it. The truth you deliver only because holding it is uncomfortable for you, so you hand your discomfort to somebody else and call it honesty. Ask yourself who the telling is actually serving. If the answer is you, keep it in your mouth.
Speak when it is kind, or at the very least when it can be said kindly. The same true and necessary thing can be delivered in a way that opens a person or in a way that closes them permanently. Both are honest. Only one of them works. A man who tells the truth in a manner nobody can receive has not told the truth at all, he has only relieved himself.
Speak when there is nobody else to speak. This one matters more than the rest, and it is the one that will cost you. When a person is being wronged in front of you and everyone in the room has decided to look at the floor, that is not the moment for the restraint I have been teaching you. Everything I say about holding your tongue is void the moment someone weaker than you needs a voice and yours is the only one available. A man who is calm and measured while injustice happens in his hearing is not disciplined. He is a coward with good manners.
Now, when to hold it.
Hold it in anger. Every single time. The words that arrive in a rage arrive fully formed and feel enormously satisfying, and they are the ones that end marriages and friendships and the trust of children. Nothing said in that state has ever improved a situation. Wait until the heat has left you. If the thing was worth saying, it will still be worth saying tomorrow, and tomorrow you will say it in a way that can actually be heard.
Hold it when you do not know. You will feel a pull, in every room you enter, to have an opinion about everything under discussion. Refuse it. There is no shame at all in the sentence I do not know, and a man who can say it plainly is trusted far more than the one with an answer for every question, because people can tell the difference and they always have been able to.
Hold it when it is another man’s business. What you know about a person’s affairs is a trust placed in your hands, and the appetite for repeating it is one of the strongest appetites there is. It feels like nothing when you do it. It is theft. You are taking a thing that belongs to someone else and spending it for the small pleasure of being interesting for a minute.
Hold it when the room is not ready. The same words land differently in different hours. A thing said at the wrong moment is wasted at best and destructive at worst, and knowing the hour is most of the skill.
And now, how much.
Say less than you know. Always. This is the discipline of a lifetime and you will fail at it constantly. Most men tell you everything they have within twenty minutes of meeting you, and there is nothing left afterwards, and their words have no weight because they spend them all. When a man who speaks rarely finally opens his mouth, a room goes still. That is not a trick. It is the natural interest rate on restraint.
And notice this about the loudest men you know. Volume is almost always compensation. The one who talks over everybody is rarely the one who understands the most. He is usually the one who is most afraid of being found out, and he has learned that if he never stops talking, nobody gets a chance to look closely. Real knowledge is calm. It does not need to fill the air, because it does not need you to believe it.
The last thing.
Every word you say is being written down somewhere. I do not mean by people, though people remember far more than they let you know. I mean that nothing is lost. Not one sentence you have ever spoken has fallen out of the world. The angel on your right and the angel on your left are not a story we tell children. Whatever you say is recorded, and you will one day stand and read your own transcript, and there will be no context available to you then and no explaining what kind of day you were having.
You will be asked about your words. Not your intentions, which only you could see. Your words, which everybody heard.
I have given you enough for one evening, and I am not going to end this with an instruction, because you are grown and you would only resent it.
I will leave you with a question instead, and I want you to sit with it in the car on the way home and then never answer it to me, only to yourself, every day, for the rest of your life.
Of everything you have said today, from the moment you woke until you walked into this room, how much of it was true, and necessary, and kind, and how much of it was simply noise you made because the air was there and it was free?
