Annoying Habits

There are so many things that have the potential to annoy your roommate/dormmates.  I would be annoyed how much of an imposition it is to live in a dorm, but that would be an annoying habit.  Annoying things include: anything that makes noise, anything that causes you to only be partially dressed, anything that makes a mess, anything that prevents your roommate from sleeping or studying.

Some examples are:
- Playing an instrument
- Turning the light on early in the morning or late at night
- Leaving clothes on the floor
- Exercising in the room
- Leaving your door open when playing music
- Letting your ostriches poop on your roommate's bed

The thing is that being annoyed by your roommate doing any of these things would also be considered an annoying habit.  It's like a viscous time-space continuum circle of annoyance.  The key is to take turns.  If your roommate tells you that something bothers him/her, fix it and then you can tell him/her about something that bugs you a few days later.

It goes like this:
Person 1: It bugs me when you play that screamo music
Person 2: Ok, I will fix that
two days pass
Person 2: Would you mind not leaving dirty dishes on the counter for days at a time?
Person 1: Oh I'm sorry!  I'll wash them
a week passes
Person 1: When you get up before me, could you not play with your maracas?
Person 2: Shoot, I'm such a spaz.  I'll make sure I stop that
etc

If there is something that you do that annoys your roommate that can't not do (like drying your hair or practicing an instrument), try going somewhere else to do it, or choosing a time to do it when your roommate is in a class.  You could also compromise by suggesting that she can obsessively clean whilst you play your instrument.  Or you could just murder her in the night and then pretend you didn't.  That always works too.
