Honestly half of my stress could be cut out if my roommate wasn't an extrovert. Extroverts tend to babble and repeat the same information over and over again. I like succinctness. Tell me something succinctly, no more than once every few hours (preferably once a day or less), that's what I like. I loathe and detest having to sit there for half an hour suffering while the same information is repeated over and over again. With an extrovert for a roommate, I have to put up with that shit several times a day, and it's extremely aggravating.
The worst part is that the more frequently someone tells me to do something, the less likely I am to do it, because of the combo of stress and that part of me that loathes being told what to do.
