Oh dear...I'm going to have to be really, really careful here...let me just start by saying that this is entirely my opinion. I'm not trying to speak on behalf of anyone else.
I live in London, and for the past eight years, I've alwaysworn an iPod whilst on public transport because I cannot stand to hear the aggressive, inpolite and frankly stupid conversation of teenagers.
All teenagers
I will be 100% honest with you...the difference between black and white and Asian is fading fast. They act the same, dress the same, and have that same aggressive attitude.
My brother and I are polar opposites. If he moved in next door to you, you'd sell up and move house under cover of darkness.
However, if I moved next door to you, you would simultaneously look forward to increased property values, whilst also worrying that your herbacious border wasn't looking it's best.
I think it's incredibly difficult to summarise a very disparate group (because 'black' encompasses West African, East African, West Indian...etc etc).
It's also temptingly easy to summarise a disparate group of people.
Just re-read my post...very wishy-washy I'm afraid, but it's really difficult to summarise 40 years of what I've seen in London concisely.
