>>My kids never threw public tantrums.<<
Neither is this child. He’s three, he is disappointed, toddlers cry. Period.
But the big part of the story is that the ball was thrown to the kid and the adults next to him took it. Did ya expect the kid to tapdance about it? He’s three.
In the olden days, when an adult got a ball, it was tossed to a kid. The woman will get her reward in the afterlife.
I didn’t watch the video. Your description changes the whole image in my mind. It would appear that the two year old was the adult.
