I'm taking higher level math and statistics classes right now, and a few of my peers asked me for answers to homework. Reluctantly, I gave hints and answered direct questions, unless they asked, "What is the answer?". I'm beginning to doubt whether or not I'm doing the right thing. Without thinking, my usual response is to help others. I guess on an unconscious level, I want people to like me. My thoughts are that I shouldn't help them. I don't expect to ask them for any help, and classes are getting harder. In a sense, I am competing with them, and in that context it makes no sense to help them. I'm not sure what to do, and I think this will happen again. In situations like this, what do you think is the best action, and why?
