"You can't get better teaching than that"

I'm somewhat surprised that NPR would be crazy enough to post a story that Glenn Sacks sarcastically called a Heartwarming Tale of Domestic Violence (and why, oh why, does the grandfather here have to be a Presbyterian pastor?)

[O]ne day while his grandfather was translating, he and a cousin were playing and distracted Ahmaogak so much that he jumped up and threatened to spank the two children.

"Before he could come near us, grandma come running around the door from the kitchen holding those real big handle straw brooms," he says. "When grandpa saw that broom, he just turned away from us, put his head forward and waited for my grandma," Edwardson says, and "she hit him with that broom so hard it broke. He never said a word. He reached over, picked up the broken part and gave it to grandma, put on a jacket, walked out."

Twenty minutes later, Edwardson says, his grandfather returned with a new broom, which he gave to his wife, then turned his head for another blow.

"Grandma just laughed and told him to get lost," he said. "I mean, that's the kind of love my grandma and grandpa had for each other. Never raised a word against her, never said anything against her. But when she hollered, he was ready for her broom.

"That's how they were, with actions. That's how they taught us, and you can't get better teaching than that," he said.

Flip the roles around and I'm sure that you'd be talking about jailtime rather than how you "can't get better teaching than that"
