Last night I got one in between aikido and eskrima, so I spent the hour-and-a-half class trying to relax enough so that I could participate. I would have just gone home, but the classes are absolutely vital for my psychological health, and turning into a bed-slug is just a bad plan all the way around.
So here I am, at work, contemplating skipping aikido for the night so I can get to bed at a decent hour. And get up and go back to aikido for open gym on Saturday. Gotta get ready for that belt test, whenever they decide to set it.
On the plus side - I got the first draft of the unicorn-pegasus-kitten story finished!
