Used to live in Hackney and did love it. However, we moved out and it was only then did I realise the subtle differences as opposed to the obvious ones. Its not like one is good and one is bad, but I think like anything in life you can't really appreciate the subtle differences.
For me, not always checking who is behind you when walking home in the dark. I was not paranoid, but it was strange how I realised that this was something I always did as a matter of course. I didn't realise I did this till I moved out.
The sense of space. Birdsong in the morning.
Seeing young kids hanging out, confidently. I live somewhere where children go out to play with their friends at around 9. We see groups of children hanging out in the park, going to the cinema alone. Its a joy to see and hear. They are ferried around by their parents.
At school, its not the obvious things. I used to help out at a school in Hackney and the differences I notice in my kids current school are the extra curricular ones. The school trips, the art department, the pottery kiln, the playground, the quality of the books. All in primary school.
Parks not covered in dog shit and beer cans.
I do miss lots of things about living in Hackney but then I simply go there, for a day out.
I don't think we moved out for the 'fear' I think we moved out because we wanted a change. I'm born and bred in London and I think I simply wanted to move somewhere else.
