Once upon a time, there lived a brother and sister. They used to fight a lot. I mean every brother and sister fights but they basically hated each other. As the time passed, they grew and the brother now went to abroad for his studies. They both were very happy that now they don't have to face each other everyday. In the beginning they both were very happy in their lives but soon started to feel lonely. Brother was visiting many new places but always thought that if his sister would have been there it would have been more fun. Same was with the sister, she was missing her brother. After five years brother came back from abroad and now they spent as much as possible time with each other. Because life is very short.

Moral : When you have something, you don't value it but when you lose it or when you don't have it. You get the real value of it, that how precious it was.
