I was waiting for someone to encourage this young man/woman to avoid arrogance and smart-alec remarks to anyone, not just those older, and especially a mother
said he was as sweet as could be. I.E respectful.
When someone is'nt minding their own business, telling them so IS kind and respectful, enabling that kind of rude, arrogant, untrained, direspectful behavior is not, it merely encourages them to go on in life thinking that getting in others business is OK. He got a lot more respect than he deserved. Age has nothing to do with it.
