I believe in moderation in all things, even moderation, meaning occasional excess is ok, but preferably not regularly done.
Under normal circumstances, I judge people very little. Some of my friends are insane, in my opinion, but still my friends. But, when looking for someone for a long term relationship, I am insanely picky. I will say no to most people, if you want to know why I said no to you, ask, I will tell you. I would like the same. You can not better yourself if you don't know what is wrong.
