I have a confession to make. I'm harboring an Inner Slacker. She's about 19, prefers to sleep until 11 or so, and would eat pizza and cheeseburgers every day if I let her. I keep her pretty well in check during the week, but if I let my guard down, she runs rampant on the weekend.
It's the same deal every week...around 5:00pm Sunday the realization strikes that the weekend is almost over and the work week is about to start again, and the Slacker gets cranky.
