I was walking back from the class. In this first day of the lecture, I got many things to do. It was not my intention to kick that something but I feel I want to kick it. An empty can! The can is rolling in front of me, making such a very annoying sound.
Ok, what is a can? Actually, according to Wikipedia, a can is an air-tight container for the distribution or storage of goods, composed of thin metal, and requiring cutting or tearing of the metal as the means of opening. Cans hold diverse contents, but the overwhelming majority preserve food by canning.
"Tin" cans are made of tinplate (tin-coated steel) but may also be made of aluminium or other metals.
So, from this we know that a can is something quite good in making. We used to storage milk in it if it is a milk can. Then, the carbonated drinks also used tin can for a very good packaging. In this case, the tin can is useful if it is full with water, we can suddenly drink water from it. In contrast, how about an empty tin can? It just giving annoying sound and providing irritated feeling to us. Alas, do you know the literal meaning behind an empty tin can? Hikhik, it is just like human being…….think about it……
