10 points ! Why do i hate my brothers friend? please help?

No offense. Your jealous and hurt. Its human nature don't feel bad about it. Your allowed to feel rejected. Everyone does some time. If you ever run into this situation again, just tell the dude how you feel. Worst that happens is he says no then you can move on. I think you feel you never got your chance. If you want a chance some times you have to take one. Especially when it comes from brother and sister friends. Most people won't tell their friend they think their sister is hot.
