The fundamental difference between girls and boys was filmed
Mothers of girls and boys for the most part know the differences between their children of different sexes. It’s not for nothing that girls are called “princesses,” because they are gentle, spiritual children who strive for something high. And the boys... they, let's say, just learn new things. Even where you don’t really need to know it.
This video shows what it looks like in real life. While the daughter was giving her mother a cute flower, the son was in a hurry to give his beloved mother... a poop. Cute, of course, but not very much.
