neighbor theory

my neighbors are either illegal immigrants or have obsessive compulsive disorder. why would i make such brazen assumptions? because they are always taking a freakin' shower. i can hear it running all the time. if i get up at 5AM, someone is showering. if i get up at 8, same thing. in the middle of the day, shower. at night when i get home from the gym, someone is in the damn shower. so either there are fifty illegal immigrants packed into a one bedroom apartment, or someone has OCD. or maybe they just have a bad case of B.O. either way, they need to stop. it's creeping me out.
