i am very glad i got out of the city nearly 14 years ago, even if it was only the city of Plymouth and not a larger city, there are still problems there according to friends who still live there. i was lucky, i married a country girl who didnt like living "in" the city, even if we were living in the suburbs and we were nearer to Cornwall than we were to the city centre!
i went back just after we moved here 3 years ago, it was horrendous, too many people, too much traffic, drug dealers, drug addicts and yes immigrants, all over the place, i was very glad to come home to the countryside, i couldnt live in a city again if you paid me, i think i would go mad in a week, and i was brought up in that city and lived there for 43 years!
Some people that prefer to be alone arent anti-social they just have no time for drama, stupidity and false people.
