how to deal with roommates

When I was in college, I shared a room with seven others. There we were, all fresh college students, with diffirent attitudes. I have learned that not everybody will like me even though how much I try; and vice versa. Each of us has diffirent attitures, outlooks in life, and principles. Once in a while, there will be disagreements. So how did I deal with this? I learned not to judge a person by what I see. I cannot read what's in their minds. I just try to put myself in their shoes, to try to understand them. If I still cannot understand the person, and I feel frustrated by the attitude, I pray for them. And, you know, the more you pray for a person, the more you care.
