At lunch, I was sitting next to one of my best friends, who is a guy (gasp).

Lunch monitor: *walks up to our table* Hello!

All of us: Hi.

Lunch lady: *looks at me and best friend*

Lunch lady: *looks back at me*

Lunch lady: *rises her eyebrows, smiles, and nods slowly*

Me: *bursts into laughter as soon as she's out of earshot*

Best friend: ...what just happened?
