Addendum: Fire Alarm
Obviously, there was no fire. However, I noticed two strange things when I came back to my room. First, the entire third floor smells like burning (probably caused by someone's lack of skill with a microwave. Second (and even weirder), when I came into my room, two out of three of my air fresheners (AKA: Bounce dryer sheets hanging from the fan) had fallen off. And they were there when I left. Very strange indeed.
