Marginal propensity to fail.

Oh hey! Currently having a break from Econs lecture. It's freezing here. I don't know why SIM's like an igloo. You don't bring a sweater, and you'll be close to death. Also, I have the most random friends here. It's like I know this person cause he/she is another friend's friend or friend of friend's friend. It's quite amazing how small the world is. Extremely. This is a random post but you see that picture I've posted along with this post? I don't know what's going on, help? That is one ki siao graph.
