When I accepted a position in New Zealand (it was before Skype), I was homesick for some time : seasons upside down, isolation, a new language. It took time to get used to. But it was also the end of the long winters, the absence of light for many months, and the Pacific was so beautiful.
Back in the northern hemisphere for the cold season, I realise that this return to self it causes, the desire to stay at home, waiting for the spring, all that I missed. Just like nature, the mind seems to pause to get back to basics.
