I think of myself a Londoner too. Despite my accent it feels a bit weird to continue to think of myself of a northerner when I've never lived there as an adult.
I'll fess up, I didn't like it at first. It was too noisy, dirty, slow to get anywhere. Trekking across London to visit friends made me feel they might as well live in Manchester. And the evening standard made me live in constant fear I was going to be gassed on the tube or knifed by a gang member. But then I left for 6 months and changed jobs on my return and I haven't looked back. My new job had a better work life balance and I could actually make the most of London, even on a lower salary - gigs, exhibitions, festivals, restaurants, just walking through new districts I hadn't visited before. It feels like a place where there's always something new to discover, and is constantly changing ( I actually like that, while laughing at the irish pub I used to work in becoming a twattish bar with overpriced cocktails and a silly name).
Now I have dcs I don't do quite the same things, though I do have a good network of mutual babysitting favours so can still do restaurants and gigs and general wandering now and again, and I pop to galleries and museums in my lunchbreak fairly regularly. But with dcs the same feeling of possibility exists and we're still discovering new places and making the most of all the activities that happen in a place where there are so many people. In addition we now have local friends too and are grounded to a particular area as well as London in general.
What gets my heckles up is the sort of shudder that people give when the idea of bringing dcs up in London is raised. As if living in a flat, or taking a baby on the tube, is akin to neglect and sending children to state secondary in London is a recipe for turning them into knife wielding criminals. Actually I have a house with a small garden but I'm not sure why this makes me immune from the approbation. it's only somewhere to live. Plenty of dd's friends live in flats or share bedrooms but are hardly deprived. What is this quality of life that having a 3 bedroomed house automatically conveys? I can't help but thinking the Stewart Lee sketch...
Sure, there are places where dd could have a lovely, but very different, childhood. Beaches and moors are lovely, but not everyone's idea of the only way to have a good time, particularly in winter when it's dark after school. Dd is a social butterfly and is a bit lost in a field without loads of other children.
There are places where she could have a similar childhood and a bigger house and garden, and dh and I could walk to work. I can imagine that life being perfectly workable but I can't immediately see that it would be better than what we have now. Coming home 20 mins earlier from a less exciting version of the job I have now to a house with a huge kitchen with an aga - it doesn't excite me the way I'm excited by London, and certainly I can't see the attraction of upping sticks and starting over just to achieve it.
This isn't a dig at those who enjoy living elsewhere. I probably wouldn't want to give up my life in eg leeds to achieve a bigger selection of art galleries either. But less of the "I couldn't possibly bring up dcs in London" please (aimed at the world in general not particularly on this thread). our dcs are doing just fine.
