her: did you hear what she said the other day?
me: no.
her: you were in the room.
me: yeah, i don’t really listen to what any of them have to say.
her: oh.
me: you pay much more attention to them than i do.
her: well whatever.
me: and even when it seems like i’m listening to them, i’m really not.
her: ha ha.
me: especially if i nod and say wow a lot, that’s when you know i’ve checked out of the conversation.
her: well anyway, she was saying such stupid things, i thought you heard her...
me: (nodding) wow.
