Also, to those of you who may work in seminary-type environments: please start telling students that parish ministry is very isolating, even if you're not serving in a geographically isolated area. It's hard to make friends when you're fresh out of the tight-knit group that is a seminary class. It's hard to make friends when you're the pastor (or pastor's spouse). It's hard to make friends when you don't have disposable income or much free time. Most people don't seem prepared for that shock of isolation, and have no tools for coping other than a telephone call to other friends who are similarly isolated. People need to know this so they can at least mentally prepare a little!
And to those of you looking for friends in a new place: it's hard, but please do it. It's so worthwhile to have good friends who can support you, challenge you, and all around make you a better person. Take my word for it, I'm lucky to have a bunch.
