It depends who I am with and what the issue is. My mother is quite pessimistic, so with her I find myself overly optimistic or with at least a sort of 'well if it goes wrong it won't be that bad' sort of attitude. Similarly with a friend of mine who is quite negative and depressing to be around at times, I find myself compensating for her pessimism with optimism. When it comes to issues that concern me, e.g., what mark will I get for this subject etc., however, I tend to be a little more pessimistic, well, not pessimistic so much as I think it will be bad, but while I know logically it should all turn out okay, I worry a lot that it won't.
So I guess I'm basically optimistic, but a worrier, but more optimistic and less worrying when around people who are quite pessimistic.
