Some children were not thrilled with the trade.

Malik Hall, a round-eyed second-grader, looked apprehensive as he stood in line with his favorite toy, a thick, blue gun with plastic sword underneath the muzzle. The 8-year-old was furious when his mother, Amanda, told him he would have to give it up. Yesterday morning, he tried to hide it under his pillow, she said.

“I’m worried,’’ she said. “He might cry.’’

But when it was his turn, Malik strode dry-eyed and with quiet dignity to the Bash-O-Matic and fed it the gun. When his mother approached, he said nothing.

“You don’t want to talk to me?’’ Hall asked. He looked at her stonily and left to retrieve his gift.
