How do I make a boy feel not so embarrassed about losing.

don't do anything! those stereotypical bitches! you won! so they should be praising you, you should get all the attention for winning, instead of him for losing, if he had won, nobody would have cared, but because you're a girl you can't win? how unfair is that? you have the right to be good at something! i think that's sexist and unfair, not all girls are slower than all guys! come on people!!!!!!!!!! i thought we were better than that...see that's why i hated highs-chool!
(and maybe because i was a loser) anyways, you don't bother about it! it's not your fault you won so don't feel guilty about it girl! just because guys are "supposed" to be faster and stronger than girls, it doesn't mean they always are, just like girls aren't always more compassionate or thoughtful than guys are, you deserved to win and be treated fair and square, but i guess you can't blame them ,after all that's just the way the world is right now
