Whan every foul cometh ther to choose his mate.
--- Chaucer
More than anything, if you can't pair up with somebody on Valentine's Day, know that you aren't alone. Let today be about a solidarity between yourself and all of those who remind you that you are not alone in this world, however cruel, mystifying, and inexplicable it feels. If today is about birds pairing up, I don't think anybody will mind if they flock.
So, continuing in the same vein of Valentine's Day = Solidarity, I would propose that the best LJ post today is this. Rick, I think you've definitely got the right idea.
