"Just let them keep screaming until they get tired," another said.
"I try to apologize, but if they don't want to accept my apology, I just walk away," a girl added.

The Rev. Julian Rivera from New Psalmist peppered the kids with questions from the Bible's first slaying, Cain killing Abel after God apparently liked Abel's offering of meat better than Cain's "fruits of the soil."
The kids got the theme right away - one girl said Cain was jealous of his brother - but Rivera pointed out that what Cain had really done was take out his anger with God on his brother.
"Do you see how that can happen?" Rivera asked, shifting to present-day problems.
He said the children are not too young to examine the biblical story of murder.
"Some of these children have worse stories than Cain and Abel."
