Its just sports. Do they treat u the same when u are in the
classroom, during recess breaks, after school etc? If so, then they
really aint ur friends. If they don't, then its maybe because boys
will be boys. When they play soccer or games, their will to win
always take over logic. Watch EPL or any team sport and u will
know. They will shout at the ref, the opposing team, even their own
team-mates. So u got nothing 2 worry man.
