My ds (9) has been going through an angry phase at home lately and said at the weekend that no-one will go with him when they pair off in class and he goes round the playground on his own. He has one supposed best friend, but this boy is very popular, and ds says that two other boys "hate him so much" that they suggest games to his "friend" that they know he'll hate (usually involving guns) so he'll go away. His birthday is quite soon and he says he really wants a party, but has no-one to invite. I've suggested a birthday treat, maybe just with this one boy, but he's not sure if he'll want to come and he wants a "proper party" as well as "everyone has parties".
He's always been a bit on the periphery and has different interests from the others (he hates football, guns, Warhammer and Star Wars), and he doesn't seem to want to compromise for the sake of being with particular people. He relates well to adults, but I just feel so sorry for him at present as he's really low and lacking in self-esteem.
