OK, I'll contribute.
I got such a shock on arriving back in Bracknell after Camb! I never really realised how awful it was- all the graffiti, concrete and chavs- because it was home and i never knew anything different. Now I do, and it's a shock.
And it doesn't feel quite the same as it did before. Obviously my room and so on does, but it feels like something I just have to put up with.
And I do genuinly miss all the people I know in college. Not just friends, but the random people I'd meet in the bar or bump into and say "hi!". And I miss just going downstairs and having a cup of tea randomly with people on my staircase.
lol, a chav is currently riding a motor scooter down the path outside my window.
I soooo want to string some piano wire across the path...
