My DP has a brother and a sister. The reason for the post is that when it comes to either of them having, say, birthday drinks we never get invited! The DB & DS go to each others but don't ever mention it to us. DP's mother babysits so they can all go out, but even she doesn't mention it. Does DP bring it up? I think it is so awful, and really feel sorry for my DP, that he gets left out. What would you do?
