You know you use a word too much when you hear it coming out of your kid's mouth. Billy's taken to answering questions with "sure." Well, when he answers in the affirmative.
I didn't realize I'd used it with him so much until he started saying it back to me.
Thing is, I broke Hubby of saying "sure" years ago. Of course, whenever he said it, it sounded patronizing and condescending. Now, he'll catch himself and it sounds like "shu, yes!"
