True, but if you're starting from scratch with teenagers, it might take a few fingers for them to assimilate, "Sharp things cut you."
I guess I have a different take on young people in America. Where ever I go - whether to a suburban mall or a New York City Starbucks, I meet hard-working, smart teens and young adults. Invariably polite and competent. No body parts in buckets. The kids at my local Barnes & Noble are practically literary geniuses - some writing the great American novel in their parents’ basement and the others training to move into jobs in publishing and editing (if there are any jobs in literature after Hillary’s book destroys Simon and Shuster!) Europeans who visit our country are gob-smacked by our brilliant culture of service - generally manned by young, minimum wage kids.
