Birth of the small girl

There lived a couple in a city in India, who were working and leading there happy lives, with loads of love and happiness. God blessed the couple with 3 beautiful daughter's they were very happy and loved them, they were the Apple of their eyes. However, the couple desired to have son to take care of them when they were old, but unfortunately they again were blessed with a daughter. The parents still loved their youngest daughter and gave her all the love and adored as much. Time passed by all the four siblings grew playing, teasing, fighting (as all siblings do). The eldest was the most responsible one amongst all, because she was always used to taking care of her younger sisters. They were in school including the youngest sister.
