Freaking Out

It's Sunday. A few minutes before noon. I feel like I should be doing work. But for the first time in months I don't have any work that has to be done right now.

This is kind of freaking me out. What do people do on Sundays if they don't have a massive amount of work staring them in the face? I have heard rumors of this concept called the weekend Does anyone have any information on this? Is it true? And if so, what the heck do you do?
