Okay, before I say anything. I'm gonna say that most people get part of their salary every 15 days. Not once a year.

Anyways, Where do I see proportion and similarity on this wonderful planet that we call Earth? I see similarity in twins. We have twins that work at our school. Twins are similar! And we see proportion like everywhere! I mean, you can buy a half liter of milk or a whole liter of milk. One half liter times two means you get a whole liter of milk! Uh, it's important because you do not want to buy to much milk!
