My worst neighbor I've ever had is the guy who has the apartment above me.

He's unemployed, has no tv, and has really squeaky floorboards. He spends most of the day pacing around by the sound of it, I assume because he has nothing to occupy his time.

I've lucked out with neighbors/college roommates. While there has been plenty of drugs and alcohol around, I've never had my room broken into and had stuff stolen.

I HAVE had plenty of people accidently walk into my room thinking it was theirs, but it was funny more than anything else. Besides, who HASN'T stumbled into the wrong room on campus on occasion? certainly not me
