In our society or even in the world, man and woman has different style of work, different responsibility. From the Creator a different responsibility came to woman on kid and rest made by the society. Today I am not going to arguing on that.
I point is on other side. After married a woman has to have or do many responsibility to her in laws family in Bangladesh. What about man? Why not man take responsibility towards his in law family too? Why this difference? Both are human.
