Kind of reminds me of my experience being Jewish. And there's a fun game we can play when meeting a new Jewish person called "Jewish geography" where you try to figure out what other Jews you both know or have at most one degree of separation from. It's a small world, but it's an even smaller Jewish world, so it can be really weird when you realize that the person you're talking to is best friends with the older brother of a kid you went to summer camp with. Or the cousin of someone you dated. Or went to the same Hebrew school as you, just five years apart.

Fun times.

I spent several hours in Palm Springs one day with a Jewish friend of mine from Nebraska looking for Rabbi Bob. He was sure we would find him there.
