If he didn’t offer to share, and I didn’t force him to, the other parents would think he was spoiled. But he loved that truck. Did he have to give it up just because this ring of kids wanted him to? One child kept trying to snatch the truck away. “No,” his mother said. He tried running at the toy; she had to grab him and hold him back. Finally, he released a scream that went on and on like a dial tone. I felt terrible. “Okay,” I told my son. “Let’s share.” I pulled the truck from his hands and dragged him, wailing, over to the swings.
