He lived on a nice quiet estate with just one other family. No cars, screaming kids. A nice local pub, a charity shop with nice suits.OK, so the post office was a bit cold and breezy, but apart from that....what the hell did he have to complain about ? It's not like he lived on that other estate with drunken Christians and wife beaters shouting at each other at all hours of the night.
I agree. Well, he is holding the guilt, remorse, regret, etc since abusing his deceased wife - that could explain his rage... but he was obviously angry back then too. His condescending speech with Hannah annoyed me, the 'you live in a nice home, nice neighbour hood etc, you don't know what I have to deal with, here, in the real world'. What? Annoying dogs and young people at pubs?
They were Asians from the post office, weren't they? I only realised that when someone made reference to it later in the movie.
He did have a reasonably nice house with big gardens attcahed, but as we saw with the other characters, what you HAVE, how quiet your neighbours are or whatever, is no signifier of what's going on in your head.
I think the speech was supposed to be annoying because we know for a fact that he is wrong in his view of Hannah at that point and wrong in his assumption that everything is rosy in middle/upper class society.
Also, he's angry with himself and what he has had to deal with previously in his life, the remorse and guilt that comes with that, but he sees the real world every day when he looks outside his window at the despairing situation the boy and his mum are in, being mistreated 24/7. Clearly, that angers him.
