Just need a little snack.

I am innocently sitting at my desk at rest time, finishing off my lunch with this delicious cupcake.

A student lurks nearby.

I take a bite.

A crumb falls from my cupcake and lands on my sleeve.

The little lurker creeps up, picks up the crumb, says thank you, and happily walks away to his desk, munching on a crumb.

I just about died laughing.
