Have you guys ever heard of this common myth that sons are preferred over daughters? Don't fall for it. Infact, It's actually the opposite. Because, in reality, daughters get more freedom while sons have a lot of responsibilities on them. They are expected to provide for their family, take care of them, etc. And if sons even fail to do all of that, it's a moral offense. Daughters on the other hand when they become wives get to leave. Many sons are pressured to get rid of their dreams to do what their parents tell them to. Daughters can become anything they want. Sons have to 24/7 take care of their parents both physically and emotionally. Sons who choose to go their own way are considered selfish and immoral. This article tells it all:

Oh and daughters do get to be the favorite child especially when they are the younger sibling of an older brother (I know a family like that).
