Where's Miss Manners When You Need Her?

Bringing D- home from Confirmation Class tonight, he cracked open a bag of Cheetos, which was the snack du jour for the class.

"Mmmmm.... I love Cheetos," D- said.

"I like them every once in a while but I don't like how you get all that orange cheesy stuff stuck to your fingers while you're eating them. I have to go wash my hands every time I'm done eating them."

"Nuh, uh. You just lick your fingers clean!"

I sputtered. "But after you do that, don't you have to...? I mean, aren't your fingers all coated in...? Don't you find it gross to bathe yourself by lick...?"

I just gave up.
