Very interesting thread.
First ever culture shock for me was aged about 8 or 9, (West London, 1980's) when i went to play with a school mate. C.
I had loads of other friends and loads of freedom to roam free (good old 80's!) but they all lived in the same bit of town as me, all the same 3 bed semi's.
There was a big estate a couple of miles away with a some tower blocks. I'd been past it loads in the car but never been through it/to it. Never thought about it.
C and I wanted a play date so much. I had to pester very hard to get my DM to arrange it. Turned out C lived in a flat in one of the tower blocks.
It was the first time i had to be 'taken' to play with someone and i was excited. We walked all the way and when DM dropped me off she told me i was to stay in C's flat and NOT go out roaming. That was very different from usual play dates.
When we got to C's block it was the very first time i had any awareness of my own situation properly comparison to another. It was the most peculiar feeling. An epiphany i guess.
I was very young - at first i thought
''why do people like to live here? It's horrible! Poor C. WHY does she live here?''.
Just confused.
Then it sort of sunk in over the play date that the people here were stuck here somehow. It made me sad and it made me think.
I spent the whole play date very distracted. The estate was a sink estate. Quite bad. C's flat was ok'ish. It had furniture and a telly and she had a few toys. Not many though. The flat was dirty. When you're 8/9 you don't notice much detail but i knew it wasn't right. We did a lot of standing on the balcony looking at the view. Seemed like C did this a lot. We weren't allowed to be loud or run in the flat. Her mum was in the bedroom the whole time and i found that very odd. (My DM was always 'present'. Buzzing about cooking or gardening or whatever. On hand for snacks ect)
I only ever went there once, and C's mum never allowed her out to playdates. We stayed friends at school but lost touch when she went to a different secondary.
