Not all of them, just some of the more babyish ones. I don't display my annoyance outwardly (am trying to be adult about it) but I really can't be arsed with them and when they are around I get pissed off. DS is nine and is a great wee lad but can revert to this babyish ness when playing with these lads. I'm beginning to worry that boys in general are just weird. I can get the girls so much easier and communicate with them and chat but the boys sit and make faces, giggle, fidget, talk in funny voices. It does my bloody tits in.
