1. My friend has a habit of washing the glass and plate well by his own hand before every meal. The other day, he finished washing and intended to start lunch. But where is the glass full of water he kept beside him? Oh! It's been taken by a stupid. Actually everyone would be attracted to a clean glass among not so clean galsses. So he souldn't be blamed.
2. On the lab last week Asif took Farid's calculator unmindfully to do his task. May be his sidemate was unmindfull too. The girl beside him was no different. .... After some time Asif felt need of calculator. But where is that? Hah! He had to spent an hour to find out who is the last person to get the calc.
3. A student of mechanical took my book for his Class test for a day. It was a new book. But when he refunded the book after 3 days, it was not new anymore. It seems he f...ed the book.
Probably you are not patient anymore for the rest of the incidents. So I am skipping those. In fact those are enough to have an idea about common sence of students here. They don't think about fare-unfare, don't bother about others inconvenience.
