My brother and sister are really close and always seem to be doing things with each other, like going to the cinema, meals etc and they are going to Moscow in a couple of weeks. I'm never invited and it sometimes make me feel very sad as although I know I'm older (31) and he's (22) and she's (25) they barely recognise my existence. I've tried asking them and I get a lukewarm response at best. DH says that its just a matter of age difference and that I should just be happy with my lot and accept that I'll never be that close to them.
