I remember a day when two friends of mine and I came to a class in the evening to take the exam you need to answer to enter here. The class was boring (it was something like spanish) and we three were talking and not reading off an entire page of some papers they were passing over. When suddenly, the principal came into the classroom. One of my friends pointed out that, so we, without thinking, set our things aside and standed up like we usually did when someone enters the classroom in our last school. When we realized what we had done, we promptly sit in our chairs and didn’t say a thing until the principal left the room.
