<human>: At midnight, I turned 22. I was working on some school work until midnight, when it was due, and afterward decided to go out afterward with my roommates. I had let one of my roommates, who was already at the party, borrow my costume pants. Since I decided to come out I brought him pants so I could trade back for my costume pants.

We went into the bathroom where he set my wallet on the counter during the pants switch. I forgot to grab it on the way out, but noticed as I walked into the next room. I went straight back to someone occupying it and waited. I went straight in and grabbed my wallet. I didn't even thinking someone could have already taken the money out of it...but I was wrong, because someone had. This guy was definitely the only one in there between me leaving my wallet and retrieving it. Sadly, I didn't notice the money was gone right away. I remember what he was wearing so we're asking people who were at the party if they knew him. So far nobody who lives there knew who he was. We're still waiting to hear from other people at the party though.

Can you give me a shortened version of the text?
<bot>: I left my wallet in a bathroom at a party for less than three minutes. Only one guy had used it in the meantime. When I retrieved the wallet all of the money in it was gone.
