Do u know a site that teaches u the rules of etiquette?
Well, you would probably be best off just looking up the specific type of etiquette you’re looking for (like table, wedding, e-mail, bathroom, business, etc) or getting a book like “The Everything Etiquette Book,” but a web site that I like is http://www.drdaveanddee.com/etiquette.ht… which uses a category format and then questions and answers within each category.
