Me: Wow, Teagan has a stinky bum.
Buddy: She sure does. Remember that time this morning when I changed her and we didn't think she was poopy but she actually was?
Me: Are you casually throwing out the fact that you changed a stinky diaper already today, passively aggressively inferring that it's my turn?
Buddy: You see right through me.
