I hate it when I (a) work during the week at the bookstore, because we never seem to get out of there before 11:00 pm, (b) stay up late to watch the TV I missed while at said bookstore, and (c) go to bed after 1:00 am, only to be kept awake by a needy cat who desperately craves constant petting when I'm in bed. Then, after I managed to fall asleep an hour later, the cat woke me up an hour after that to meow and demand more petting, which I refused to give her. She then tried knocking things off the bedside table, so I kicked her out of the bedroom and closed the door behind her.
After all that, my foot started spasming along the outside edge (which it tends to do immediately after I get home from a long shift at the store, not four hours later) and wouldn't stop for at least 30 minutes, until I finally got up and squeezed the muscle for some time until it stopped. Only then could I fall back asleep.
Like I said, gronk.
Only good thing is that I'm leaving at 1:30 to await delivery of my new TV!
