If you ever do that thing you swear you'd never do . . . you know, that gross thing your parents did to you to get the little smudge off your face, like lick their own thumb and wipe it on your face . . .
If you ever do that to your 2 year old in a moment of desperation, be prepared that she just might try to do it back to you, over and over and over and over again as she giggles and giggles and giggles.
I'm just sayin'.
