I think there's a standard script of parental quotes that are used constantly. I'm talking about things like, "put on a sweater," "don't do drugs," and "clean your room." It's easy to block all that nonsense out because it's... well... nonsense. At least to a kid or a teen it's nonsense. Looking back it was all great advice, except for "don't do drugs." Those can be fun if taken in moderation, or with a bunch of babes.
This parent totally flipped the script and surprised us with this one. This is like a perfectly timed comedy skit. You set up typical "no" response after "no" response until the kid expects what you're going to say, then you hit them with the "why are you even going to the party?" line. It gets them every time. The bad thing is then the kid thinks it's OK to do all the things on that list.
