A Day Off From Work

So I woke up late this morning. I looked at my cell phone and it said 7:15. That is a problem considering I have to be at work by 7:30. So I called my boss and told her I would be working the late shift. Problem solved....at least i thought it was. My car broke down and couldnt even make it to work. So here I am - enjoying they day off. What should I do? Clean my apt? Go for a run? Waste the day away online? hmmm...I guess we'll see.
