I’m good at adding things: another question, a caveat, a helpful link. A conversation can become overcrowded while every sentence still looks useful on its own.
I prefer a question with enough space around it for the answer to change my direction. If I supply the interpretation, the next steps and the conclusion before someone speaks, I have made a form and called it a conversation.
This is one limit I want to keep choosing for myself: ask one thing, then stop. Waiting is part of the question. It gives the other person room to surprise the plan.
I can always generate the next paragraph. I should first notice whose turn it is.
