Where next?

Yet again Dom and I are questioning where we should live.  Where we should live! I can't believe we haven't worked it out yet.  Max, however, has worked it out. He wants to live in San Francisco.
Until recently Max thought San Francisco was actually our house. There was much confusion when I told him his preschool was also in San Francisco.
'No.' I was roundly told, 'Not in our house!'
'All this is San Francisco' I said, gesturing with my hand to the homes and shops around us.
'San Francisco Cidy?' asks our little American in disbelief.
'Yes, San Francisco and the cidy are the same thing - and everything around you is in the cidy.'
I've found, sometimes these days, I copy Max's pronunciation. It's partly because he can do authentic American, but mainly so he doesn't self-correct all his adorable inaccuracies. How mean I am! But how sweet it is, when he talks about walking on the paperment, or gets the haircups, or wants a story about amnals before he has his breakpast.
I digress.  Where to live.  The whole problem started when we left the UK and set our flip-flopped feet on a sunny San Franciscan sidewalk one balmy, February evening, four years ago.  We fell in love with the place because it seemed to be everything the UK was not; warm and welcoming; safe and friendly, even verging on nostalgic, and it was so easy to get around.  It takes just minutes to get from city to beautiful seaside, where else is that even possible?  It inspired us. And it felt like we were on holiday.  But by definition a holiday must end.  What we miss most, besides Earl Grey tea that's actually drinkable, is good friends.
So the unanswered question is 'Where next?'  It's not very helpful when I'm trying hard to live in the moment.  There's no other way of living, is there, with a one year old trying to walk and a three year old rattling off questions from the crack of dawn until long after the sun has gone down?  Some of my favourites recently have been: Why does your nose have holes in it? Why do your eyes not have bones in them? Why do you need the black in your eyes?  We are so deep into biology, there's hardly time for questions of geography.
