With the New Year rapidly approaching, it's a good time to reflect on the past year and think about all the people who have helped you get through it -- and how best to show them your appreciation. "The root of the word gratuity is gratitude," says Daniel Post Senning, great-great-grandson of etiquette empress Emily Post and coauthor of the 18th edition of "Emily Post's Etiquette." "An annual or holiday tip is an opportunity to really think about the people who are oftentimes the most important people in our lives."
Your hair stylist, babysitter and trash collectors, for example, have helped care for you, your kids and your home, respectively. (See our comprehensive list of people you should consider tipping for the holidays.) It'd be nice of you to thank them.
