I have an exam tomorrow, so I don't feel like drawing anything. I thought of combining studying with my countdown to Christmas, but decided against it because then I would have to draw, colour, scan, edit, etc. So much effort! Instead I will describe to you my nerdy drawing.
Santa is sitting at his desk pondering the best use of his time. [Insert production possibility frontier in a thought bubble]. He can either spend all his time answering letters from children, or he can monitor the elves at the workshop.
Oh economics. Oh joy. Okay, back to studying, and wish me luck tomorrow!
