The basics of etiquette have been largely forgotten by the younger generation.
The older generation may well remember some of the following: Don't point - it's rude Don't smoke or eat in the street - it looks 'common' Don't talk with your mouth full - disgustingly, you may spit some of it out!
Don't shout - Keep your voice down Don't interrupt - it's selfish and ill-mannered Don't swear - it impresses nobody (it's the language of low lives and those with a limited vocabulary) Open doors for the elderly and for women Hold doors open for whoever is following you in (or out)- don't let it slam in their face Use please and thank you Don't gang up on anybody anywhere Don't talk behind other's backs Turn away from people, food and the phone when you cough or sneeze Show respect for those older and wiser than yourself Without respect and consideration for others, we are nothing but savages.
There are some modern considerations too: Rules on the use of Telephones and Mobile Phones (Cell Phones) Rules on the use of Answering Machines & Speaker Phones Road Etiquette Neighborhood Noise - loud music at all hours And many others that you can think of by yourself People don't care how much you know; they don't care how rich you are. And caring about others is what manners is all about. It will improve your relationships with people immeasurably when you show them that you care about them!
Try not to be messy Show consideration for other people’s feelings If there is conflict, do not get personal in your remarks It is extremely rude to arrive late for a meeting It is ruder still to not attend at all.
