There’s nothing to writing. All you do is sit down at a typewriter and open a vein.
— Walter Wellesley “Red” Smith
I’ve got a post half-written. I can’t finish it, though, because it’s making me cry. (It’s not related to David, don’t worry.) What do you do when that happens to you?

Been there. I type through the tears because somehow releasing a sad post to the blogosphere helps take a tiny bit of the pain with it. For me it does anyway. So let it out…finish it the best you can and let it float out here among us.
