I got invited to a party by some friends. I felt a little down because I got invited and I didn't try to get my brother an invitation.
Do your friends not get along with your brother?
Well, I just don't think they are as good of friends with my brother..but I think they should still include him.
Makes sense, it's hard to bring things like that up with friends, but if you explain your feelings to them, I'm sure they'll understand.
