I think you are referring to manners? Like covering ones mouth when one coughs or sneezes?
Manners use to start young.

Yes, and not vibrating the car next to you with your $5,000 sound system. And like not blasting down the road with an exhaust system that shakes the windows in the house you just went past. And like not throwing your butts, beer cans, and dirty diapers out the car window as you drive along. Those kinds of freedoms some people demand are their right. You know, the ones that insist "they can't tell me what to do or not do."
A very long, new thread could be devoted to this.
