This is more of a rant but am more than happy to be told that I am being U...
My brother; 21, never held a job down, got kicked out of school before sitting his GCSEs because he could never be arsed to get out of bed to actually go to school, got kicked out of college for the same. Treats my mum's house like a doss house, talks to her like shite, recently been dumped by his girlfriend for being a serial cheater. He's a delight, as you can see. 
He was due to go to Brighton Uni' in September (managed to get accepted on a music course, he is a bit talented in that area). After my mum and he had a barney over his treatment of his ex-g and people in general, he flounced off to Brighton a month early when mum was away for the weekend without telling any of us. Mum was gutted when she realised and cried for two days. He's bee there two weeks, hasn't contacted any of us but has been bragging at regular intervals about how great his new life is (funded by daddy, of course) hasn't even sent me a message to ask how DS is, despite the fact that he supposedly loves DS (and DS worships him)
Now he has announced that he is coming back for a few days this week. Mum is obviously over the moon that he is coming back and wants to bring him to my house, thinking that I will just forget that he's left DS heartbroken and asking where he is. I don't want him at my house while I feel like this and nor does DH. It's like everyone is supposed to forget what an arse he was before he went just because he upped and went without a word but has now deigned to return, we should all be celebrating like he's a soldier returning from war. 
Sorry, don't even expect a reply to this long and dull rant, just feel better getting it off my chest...
