Take the day off or Sit at home an work on my tan?

Unlike most people, I have the great joy of picking the days I want to work and my company is ok with this, this is why I love my job!

I could go in today work my butt off so I can have Fri off, or take today off and sit in yard working on my tan.

What to do? I think Im going to go sit in the sun for a few hours, then head on to work! An maybe work half day on Fri morning.
