Yesterday, I was supposed to do my billing but I was feeling a little tired so I thought I would take a little nap first. Woke up at 4:30am. Some nap! Too late to do billing, so I have to do it today for sure. I must have been really tired. I usually sleep in a lot on the weekends, but I didn't this weekend cause I had so much stuff to do. Guess that lack of sleep thing catches up to you eventually.
