Her: Mommy, look! He put his booger on his leg all by himself!
(I check out the situation and, sure enough, my son has a slimy green booger stuck to the underside of his thigh, which seems like an odd place for him to put a booger. Not to mention that he hasn't quite gotten the hang of nosepicking yet.)
Me: Are you sure that's not your booger?
Her: (not missing a beat) I think he grabbed my booger and put it on his leg.
Me: Are you sure you didn't put your own booger on his leg?
Her: (again, instantly) I don't remember.
Should I be troubled, or proud?
