Summer sunshine

In our room, from the start of classes, we don't have electric fan. We suffer while the other students on the other room feel cold. And our teacher took pity on us. ^^ then we had one electric fan. we are still not satisfied. then suddenly. the former section who used the room let us borrow their electric fan. A little bit, we are satisfied. we cannot complain about that.Days had pass and we became careless. We always left our electric fan ( we just borrow that) open. so our adviser gave us another chance. and we left it again open. the our teacher gave us another chance.And days had pass again and we suddenly forgot to turn it off!then our teacher wrote a note on the board that we cannot use it anymore. it is our fault. we admit it. sorry ma'am. another chance??? ^^
