KABOOM!

I just recently experienced my first roommate explosion, which I somewhat found annoying. I'm sorry, but if you don't like confrontation and expressing things that REALLY bother you than is that really my fault? Is it my fault that you hold it in so long and when you finally decided to say something you explode at the person? Does anyone deserve to be talked to in that manner when they were never privy to this issue so they were never given the chance to work it out? Is it worse to be "confrontational" or to be quiet about things and letting it fester until they explode on unsuspecting people?
