You failed why?

         Why is it that people always try to place the blame on others for their own mistakes? To make it worse, on top of blaming somebody else, they run around behind that person only telling others how they feel. I personally hate those cowardly people who will not stand up for what they feel and instead make sure the person finds out indirectly.
         Today we had a test in English about various British authors of the 1600's and 1700's and their works. We had been studying the material for a little more than a week and as a class, we were told yesterday about the test. A bit unreasonable, but also understandable considering you can walk into a college class and have a test handed out that no one had a clue about. The test was difficult but in no way impossible. There is a certain person in this class who have, how shall I put this, disparaging feelings for, which I shall leave to another day. Supposedly, this test was only given because I had the worst grade and I must get special treatment. I would not call special treatment another test, but I certainly was not the only one that needed to improve my grade.
         The test wound up being relatively easier than I expected once I completed it, but others did not have the same opinion. One certain person, who I mentioned earlier, was on the verge of tears afterwards. I come home in the afternoon only to find out later that this certain person is blaming me for her failure. Last I checked, I did not take the test for this person. I did not take poor notes for this person. I did not prevent this person from studying or preparing for this test in any way. This person failed, but cannot admit that she did not prepare well enough. Instead she blames me, as if the test would not have happened at all if I had passed the first time.
         Today it seems too many people are too lazy or too busy with work or simply procrastinate until the point that preparing for a test is the only thing they have left to do. The only problem with her is that she fails in multiple areas everyday; it seems life is one of those areas. Once again, my true feelings about this person are best left to another time.
         To conclude, why do people not keep to themselves and instead of trying to blame others for their failures in life, work for what they want to accomplish? That That is something for which I simply do not have an answer. If a test is the worse thing at which I ever fail, I must be accomplished compared to some.
