is there such a thing as blogger's block?

I have nothing to say lately. Don't really know why. Funny things aren't happening to me, maybe? Or I'm not able to see the humor in things because I have so much work to do? I have been experiencing a great deal of anxiety about writing lately, in part because I'm not getting very much of it done. But who wants to hear about that on the blog?

So I'm blocked. Nuthin' to say except I'd better get back to grading all those essays. grumble grumble.
