In just a few minutes, I'll be heading out the door of my Istanbul daire (apartment) to start the long trip back to San Francisco, my first visit home in almost a year. I'm excited, of course (friends! food! drinks!), but also a bit anxious, for reasons that are difficult to pinpoint or explain. I was discussing this recently with another ex-pat, who said that "you know you've changed" from your time abroad, "but you don't know how" until you go back. I guess I'll find out soon. I hope it's for the better.
