Learning natural English is a skill common to any individual living in an English-speaking country. This English is learned through daily contact with people who speak English. With this we can conclude that natural English is learned, by us, since our birth through living with our family. Thus, we can say that this Englishman has an informal, relaxed air and without many rules and guidelines for its use. We can use it talking to our friends, or, in common everyday situations.
Standard English, however, refers to the standard, cultured and grammatically correct way of speaking and writing in English. We can only learn this type of English through classes and reading texts that cover this type of language. It is important to learn it because formal situations, social events, academic events and even living with people in higher status than ours, requires that this type of language be used.

For example, I remember a time when I was being asked humiliating questions by a total stranger, so I lied and said that I had to go due to family issues including my mother. It is okay to lie in uncomfortable situations.
gender roles are enforced when parents or even society tells women to "act like a girl" by wearing makeup and wearing dresses and being feminine overall. This leads to men saying girls hit "Like a girl". Men are also supposed to "act like a man" and be strong and not cry or show feelings.
