Me (under pile of back-to-school paperwork): hey, what’s the kiddo’s student number again?
Him (sitting in front of the computer): you don’t have the email I sent you?
Me: Not in front of me, no. This form has a line for the student number, and we could leave it blank without penalty, I’m guessing. But since you looked it up last week, I thought you’d like the chance to mess with the office staff and just write it in for them.
Him: Ooh! Hang on a sec (begins typing furiously).
