You may come to find that 95% of people are assholes anyway. And the remaining 5% are perfect assholes. I don't too much believe in friends just different people with different agendas. I would say of all the people I've met in my life >=.01% where for any period of time actually friends.
If anything work on diplomacy and worry about yourself.
As for members of the other sex, just remember they're after the same thing you are only thing is their brains are fu¢ked.
