"What do you want?"
"I don't care, I'll eat anything."
"Okay, how about you just grab some of the cookies from the shelf?"
"Anything but those, those are gross."
"Okay, you've got to tell us *what* you want, I can't randomly guess if you're just going to say it's gross."
"I don't know what I want!"
"How about pop tarts?"
"As a snack?"
"On second thought, I'll just have nothing."
Child, I'm not asking you anything difficult here, I'm just telling you I *can't read your mind*.
(Then again, this is a lesson that the two adult women in my life haven't learned either; why I thought the 12 year old would have learned it is beyond me.)
