Source : Google Pics In the old day, our society used to classify people's roles in terms of gender, they have their own stereotype. For instance, if someone was born as a boy, he should seem tough, strong, and say 'big no' for crying or showing their weaknesses. On the other hand, if that person is a girl, she should seem gentle, calm, stay quiet, and say 'big no' for climbing a tree or laughing loudly. How and when they did create these standards? Do they have some handbook and implement it to the life? Or what? They supposed to have a guideline, right?
