You know the idea that when you die, you will meet your lost friends and relatives in heaven or hell? Facebook is getting weirdly like that for me.

I'm finding that most of the people that I've ever known are there. All my university dorm roommates, ex-girlfriends and junior high acquaintances - smiling back at me from my friend list - and it feels weird.

Part of it is it that I've had a few lives. I've moved to different states, continents and countries over the years - and for the most part, you start fresh with friends.

Now they're all there in one place, waiting to greet me - like angels.
