My brother didn't have any friends as a child or later as a young adult- he was just too different. Hated sport, loved classical music and poetry- when all the others were footbal, ski, hockey fans and rock mad. He has many friends now- but all a bit like him, on the same wave length. He can't stand chit chat and small talk- and will only cope socially with other train buffs or mathematicians, etc- who possibly share some of his Asperger traits. But of course he is much more successful in so many ways than most with autism- perhaps because of the extent and form- but I can't help think- because he was not labelled, and was expected, and therefore 'given the chance' in a way- to live a normal life, but in his own way.
He is my half-brother- and my father 'took him on' with he was about 7- but it was not always an easy relationship, as my dad just did not understand him, and my brother him (my dad loved sport and nature- so they shared very little). But dad was very good with him- just did not have anything in common. Neither did I- and yet we were always very close- despite the 14 year gap.
