I don't think you ever outgrow the wistfulness that comes with the last couple of weeks of August. On the way home from Nantucket I stood at the stern of the ferry and watched the sun set over the water. It was the only real vacation I had taken this summer and it seemed all too short as I was headed back to the stresses of work, moving out of my apartment, and waiting to hear what would become of the next 6 months of my life. It was chilly, too, as it always seems to be out on the water, no matter how warm it is in Hyannis.
Part of my contemplative mood was caused by all the big changes coming up: leaving my apartment, people I know moving away, my own impending move to another country. It was nice in a way to have all those (big, nasty, stressful) things captured by the perennial change from summer to autumn. It's sad to see the summer coming to an end, but there are nice things about autumn, too; and in just that way, it's sad to be getting ready to leave my home for my whole life, but it's exciting, too.
And after all, summer will be back again next year.
