When you normally goes for some important work for example reservation office, school or job, you forget pens sometimes deliberately and sometimes deliberately. Then you take pen from somebody there and complete your work.
When we go to railway reservation office, leaving two, three, no one brings pen from home. At that time, it becomes a really embarrassing situation to ask pen from somebody. He will think you are not sincere. Why did not you take your pen? It happens that till you complete your work that person goes and that pen becomes yours. It is rather a profit situation.
Sometimes it also happens that you have asked pen from somebody in reservation office. He give his pen to you.Then that asking person give pen to someone else and that to someone else. Your pen goes in the hand of everybody and when you ask pen from someone else that pen returns to you .You become surprised to see your pen, given by someone to whom you didn't give your pen.
