Sibling rivalry is the jealousy, competition and fighting between brothers and sisters. At the same time, it is still a normal part of growing up and a flow of family life. Different personalities and ages can play a role, but siblings also often see themselves as rivals.

Just like the video below - the father, YouTuber Berge95 can't contain his laughter as his little daughter makes the hilariously terrible proposal. They sat together while watching her brother playing in the snow.

While convincing her dad, the little girl was so serious and you can't even see a smile on her face.

The silly little girl wanted to sell her brother for only $54, because she's going to spend it for a toy owl. The little girl will definitely win the award for the meanest sister in the world.
