Would you risk 'fight' for your own happiness?
I really have no idea what this question means. In the literal sense, I answered yes, but it depends on what you mean happiness. If I really cared about someone, I would fight for them (as I have for friends in the past), but I wouldn't get in a fight over something that might increase my happiness for no reason. Answered yes, but with clauses.
Would you approach a guy/girl who caught your eye at a party?
Have and will do again in the future. I don't really know why this is a question. I mean, it takes some guts, but there's nothing morally wrong with it, is there? Answered yes.
Would you go after a guy/girl regardless of his/her marital status?
I am one of the few people who answered yes. I wouldn't sleep with her or do anything serious, but I would be prepared to ask her to choose if I felt there really was chemistry between us. Never had this problem, not too many 16 year old brides in Canada. Answered yes.
Would you pursue a guy/girl that your good friend of many years is keen on?
This is a really tough one. Example: one of my friends was hot for a girl for a while. I was sort of attracted too. He asked her out, she said no, I ended up dating her about a month later. Nothing wrong with that. Another example. Friend of mine was working up his nerve to ask a girl out. Another, more "player" guy comes in, asks her out, she's surprised, says yes. Not acceptable to me. Ended up fighting the guy, but that's another story involving him calling my house and calling my girlfriend dirty names. Answered no.
Would you risk losing a friend if you one day regarded him/her romantically?
Been there, done that. I think that people are shallow if they call off friendships cause of that, but whatever. I probably wouldn't if it was all or nothing though. Not worth the risk of it not turning out, IMHO. Answered no.
