A teenaged customer brings a copy of Paper Towns to the register.
Me: Ooooh, John Green!
Her: I know, I love him. I'm getting this for my friend.
Me: Do you watch the video blog he does with his brother?
(Both of us: thinly veiled Nerdfighter squee.)
Me: Okay, if you could sign your receipt here... and, um, would it be really cheesy if I said, "Don't forget to be awesome?"
Her: No! ...You just kind of made my day.
The youth is out there.
