Mom and B are having a conversation about the difference between having done something and having done it on accident.
Mom — Even if you didn’t mean to do it, you still need to say you’re sorry. Just admit it and apologize.
B — But I don’t even know what “it mit” means!
Mom — What?
B — You keep saying I need to “it mit” something, but I don’t even know what you mean.
Mom — Admit. It means you say that it’s true that you did something. Like when you hit R with the Lego. Maybe you didn’t mean to do it, but you did.
B — And sometimes when R talks I don’t understand what he says, either. I think he uses words I don’t recognize.
Mom — Well, maybe you can ask him to explain, like when you asked me.
B — It confuses me. (Pause) I think the words get mixed up in his head when he’s talking.
