(A conversation between me and DD1 the other day... the boy's name has been changed because she'd kill me if she knew I'd blabbed to the world!)
DD1: I can't help it, whenever I look at Joe I can't help smiling.
Me: Maybe you think he's cute? He's a pretty cute little kid.
DD1: I don't know. Do you think I'm crushing on him?
Me: Do YOU think you're crushing on him?
DD1: No. I can't be crushing on him. He's a first grader.
Me: ...and it's not OK to crush on a first grader?
DD1: (giving me her first "you SO don't get it" eye-roll) Mom! He still has all his BABY TEETH!"
