In the bathroom I found a glass from last month’s party that was half-full of Mountain Dew.

I checked that I was alone, then I drank it.

But Melissa saw me. I looked at her calm Mona Lisa smile and suddenly I was happy.

“You sick, sick fuck,” she said.

“You’re all over the place today, aren’t you?” I said.
