I think you're getting a hard time here OP. You weren't saying is there life outside London, you were asking what life outside is like, and that is a valid question.
We moved out of London 6 years ago, and I regret it every day, but we can't afford to move back. I miss having so much going on: so many exhibitions, theatre, even some films in the cinema don't get a showing where we are, as they only show mainstream stuff.
I miss the amount of free stuff to do, the diversity, the choice on offer, the creativity, being able to live without a car, job opportunities, the amazing public transport system. And I miss my friends.
If you love London, there is nowhere like it.
If I want to see any renowned exhibitions or shows I have to schlep up to London on dodgy public transport which is unreliable at best. We can't just pop in, it takes all day. The last train home is at 10.30 which means leaving my friends early, or staying over and having to worry about overnight childcare.
I read a funny post recently which said something like: "I wear a beret in London and no one noticed, I wore a beret in my home town and a white van driver shouted "Bonjour, ooo la la." Sums it up for me.
