I live only 5 miles from where I lived when I was 14. As I wrote on another thread, by my 21 birthday I had had 21 permanent addresses, attended 10 schools and lived in 6 countries, and I would add 7 different locations in the UK.
Why do I live where I do now? Well, after university I got my first job in London. I married someone whose work involved a lot of travel in this country and abroad, this meant living somewhere with easy access to Heathrow and Gatwick and tyrains to London, so we bought a house in south east Berkshire.
DC reached 11 and I was returning to work full time and work and having to run a family taxi service because we lived in a rural area meant we moved to a house close to the centre of Reading where the children could get around on public transport..
With children independent we decided to move somewhere quieter, we have also always hankered to buy a really old house in need of restoration, but DH was still working so still had to be able to get to airports and trains to London. This pushed us to north west Berkshire and a house that just happens to be 5 miles from where I lived when I was 14.
