I don't generally like going off on tangents if the original topic is still live, but this one ended as soon as the OP saw that we weren't going to do his homework for him. I might have been too harsh; I usually am not with new people. But I really thought he was probably about a 10th grader by the way he wrote and what he seemed to already know. When I realized that he was a college senior, I just lost all patience.
