I once heard that you should only keep the friends that will help you move. As I've gotten older and have less time and energy to keep up with everyone, I tend to apply this concept. For me moving is a tedious, painful, arduous, and overwhelming task. I really don't know anyone who enjoys it. Sure there is the reward of moving to a new home / city / country / continent but first you must stare at the pile of things you've amassed over the many many years and wonder why at one point you thought it was a good idea to buy a faux leopard-skinned bean bag (not that I've ever owned one, really). Not only do you need good friends who will help pack and carry the boxes, but you need friends who care enough to tell you that you should really let go of said beanbag.
This idea came to mind because I've recently been back in touch with my good friend "Larry". We met in London but now he lives far away in a place that I couldn't point out on a map. I'm American after all and Larry would never begrudge me for my poor sense of geography. My world has been a bit topsy turvy lately (for a variety of reasons I won't into detail) and out of nowhere Larry came back on the scene as if he was channeling my frustrations.
