history: I'm moving to a new apartment in a few weeks and am so psyched about it. I'll finally be away from my loud, obnoxious upstairs neighbors! I'm moving to a new apartment in a few weeks and can't wait! No more obnoxious upstairs neighbors! That's great!  I've got to deal with loud neighbors too.  Anything specific they do?
current: Stomp around at all times of the day and night, screeching into their cellphones and playing loud video games. What do yours do?
next: Loud running toddler who pitches fits at random times, day or night.  Sounds like a similar level of noise :P
