Oh yeah, I've had too many conversations like so:
"Hey, did you ever straighten your hair?"
"Yes."
"Well, you should, it (or you) would look super pretty!"
"No, I can't, it takes forever and it won't stay."
"Oh."
And once, a girl asked me if my hair was straight when I was little, and I said straighter, and then she said "Oh, you would look SO pretty with straight hair!"
grrrrr..........
