Ah. I just did my maths homework. What's wrong with me?

Actually I just realized I take alot of things for granted -.- (when I was writing my chinese compo).
Because it's always there I just assumed it was natural, and now I'm just starting to realize it's probably not, and alot of people find it hard to realize this when I've known it all along. whee.

yet another stupid post that makes no sense to anyone except me.
