Patron: I misplaced my library card…
Me: Not a problem! Have ID?
Patron: Hmm…
Patron, digging through their shoulder bag: HMMMMM…
Patron: Oh, this is not good.
Me: Left it at home?
Patron: If I am lucky, yes.
Patron: UGH
Patron: This is very weird.
Me: Relax, pal! It’s okay, we all have weird days.
Patron, quietly: I have them often.
