What do people actually do on Sundays?

For me, it's an opportunity to breathe and relax as there usually is nothing on Sundays. Finally, I can catch up on my studies, or laze around to do nothing but mainly i just wanna rest. Today, however, I was completely distracted because my monkey mind wouldn't rest. Numbers dance around in my eyes because they've abandoned me some time ago. Carbon atoms and benzene rings make funny shapes to sneer and jeer at me because  they know I can't concentrate. I'm buried deep in guilt but no matter what I do, I can't concentrate. To make matters worse, I'm here, blogging.
