Best Friends

Why does alot of stress and a small conflict pull best friends apart? My best friend kendall and i have been friends for years. We work together hang out with each other we are both excepted into each others familys and no one would have ver thought that friends like us could actually have a real fight and not talk to each other for an extended period of time. Well it's les mis time comming about and nothing is working acording to plan we are in a major crunch and our teacher is kinda pushing all of us to the edge so that things will get done. Well a small conflict came up about having someone in the booth to call some of his cues during the show and because we are good friends i got put in charge of telling him that this was how it was going to be so just sit on your ass and deal with it even though i did not agree with it at all either well anyways youget the picture. so we kinda havn't been talking for a long time now and its hurting the show too cause we can't work with each other any more but yeah. i think that when we are all under alot of stress and are being pushed to the edge and really can't deal with it anymore and then get pushed even more is when you kinda just blow up at the first theing that comes in site doesn't matter what it is. But yes that is my reasoning for why friends get pulled apart sometimes over stupid things.
