When you ask a question, are you trying to change your understanding...or theirs?
Teaching by asking questions can cause learning breakthroughs. Too often I see people trying to manipulate others, which can backfire spectacularly.
I ask a lot of questions because I genuinely want a better understanding, not for the other person, for me.
Recently I was with a person who was waiting to be manipulated. That got to be Monty Python funny.
Sometimes a question is just a question.
