Week 12 - my first visitors came and went and it's funny how I feel about that. I've settled in well in China and have been waiting for the inevitable bout of something, but it never happened. And now as I'm hurtling towards the airport, I feel a little melancholic. Maybe not 100 per cent about home but perhaps it is more about all the things that happened before I left and when I got here. The promises and unpromises. The packing and the unpacking. The staying and the leaving. And the reality that here I am, in a life that is different to everyone but me.
