For me, it's been the combination of a very busy week, and also having my parents visiting from New Zealand. In truth the last week has been easy on me - as Mum and Dad have been staying with my brother (who is also settled in the UK). My week was normal.
Tomorrow they come back to London, and back to me for another week and a half. And then it will be goodbye again - for who knows how long. One year, two years, three?
And that is the burden of being an expat and living abroad. Every day I weigh up the pros and cons. Travel vs family time. A job I love vs settling. Living in one of the biggest cities in the world vs one of the smallest.
Does living abroad make the heart grow fonder?

Ten years ago I would have sworn black and blue that I would never return to New Zealand to live. The world was far too exciting to be stuck in the furthest corner of the globe, pretty much twelve hours flight from anywhere interesting.
These days I'm not quite as certain as that. The decision is not quite as black and white, and the topic of 'where are we going next?' is a often debated subject that sends us to sleep at least once every few weeks.
What about you? Do you live away from your country of birth? Or would you?
