• When people open things from wrong end

Some people are very careless while doing regular jobs. They do not give attention to small things. They become angry on such stupid actions. As sometime you open the packet of lays from the wrong end, though there is nothing bad due to this but when you do this, the lays inside the packet spread on the table. That looks weird and the table may not be as clean as you can eat that lays. Because of such stupid action you will not be able to eat the lays and you have to buy the new packet. This makes you unhappy and crazy.
