Brothers should take care of their sisters always.It is fortunate to have daughters, these days many people are feeling. In India, in any household daughters are given good respect. The parents will see that their daughters will get married to a boy from a respectable family. Even after marriage they will bring them to their houses for all important festivals and make them happy. They will continue this practice till they are alive or as long as possible.
For any lady after her parents, her siblings are important. So she will always think about and wants to spend some time with them. Especially brothers should think about them and continue the practice of inviting her to their houses and see that she will be happy. That will be good not only for the family of the sister but also for his family also.
So we all should invite our sisters to our house at least once a year. I hope other members of ISC will be in agreement with me in this aspect.
