Okay, me and one of my awesome friends got to her house at around, I'd say 1:20 am.... We get out of the van and walk up to the door and her mom realizes that the door lock was different. Thinking they changed it on her, we got out back and see if that key worked. Well, no luck. Looking at the mailbox, and then the apartment building number, we finally realize that we were at the wrong building. It was the next one. Not to mention we made fun of Mary and Amanda for doing it just the day before.
