Sadly, I have this unfortunate habit of being at work instead.
Every once in a while, I manage to arrange things so that my work week is Tuesday - Friday, giving me Monday as a productive day to myself. These times are pure happiness in a bottle.
Unfortunately, so far they've been cursed to be maddeningly temporary, by things such as having both cars die simultaneously so I have to go back to work to make the car payment, or by the company being dissolved because of the collapse of the dot-com bubble.
This last instance ended up with a year of unemployment followed by the agony of Starbucks, making me paranoid about what sort of horror might befall me if I tried to arrange the situation again. Unsatisfied as I may be with my current circumstances, they are at least stable, well-funded, and don't leave me battered and bruised at the end of the day.
