Brother supports the sister

As we know brothers and sisters are the real roots of a family. Both of them are required for the supportive firm. Malathi and Ravi were true brother and sister. The sister used to help her brother while going to school and coming from school. One day, Ravi was injured while playing at school. His friends reported to Malathi. She went to her brother and asked the Nurse of the school to dress his wound. The brother felt very emotional and realized that when he is in trouble he will be cared for by his only sister.
