If two people really like each other they won't care about the consequences.. If you have a crush on someone you just don't care that it might be not that smart to hook up with her. You will probably regret if you don't give it a try. In high school I had a crush on one of my classmates. Small town, small school, small class. As you said: everyone knew everyone's buisness. They told me not to date that girl because eventually we would break up and it would suck to see her every day. Of course I didn't take that advice and started to go out with her which was a great decision We were together for more than three years, we finished high school toghether. I would regret it if I missed out on that relationship.
