Should I tell my girlfriend that my teammates think her male friend is gay?
Are you sure they think he's gay?
About 20% were sure, the others not so much.
It is wrong to gossip about other people. You should mind your own business.
I'm going to tell her anyway and see what happens.
Someone's sexual orientation is no one's business unless they want to share it. Spreading unsubstantiated gossip can be very destructive. Why not focus on more positive endeavors?
