As a youngster, your child never doubted the magic in "please" and "thank you," but high school culture transformed her into a sorceress of slang and slouching. Enrolling your son or daughter in a class from Etiquette Femme will help cast a counter-spell, as your teen will learn to become a magician of manners. With today's deal, get a four-hour etiquette class for teenagers or adults for $37 (regularly $75), or turn politeness into prime bonding time with a four-hour mother-and-daughter etiquette class for $57 (regularly $115). Led by Akilah Easter, who has 15 years of charm school experience as both a student and instructor, the class will cover everything from table manners and formal dining behavior to standing, sitting, and walking technique and even social media manners. There will also be a section on formal introductions and giving professional presentations -- though each lesson is adjusted to accommodate the students' needs (classes have up to 20 students). Held on Sunday afternoons from 1 p.m. to 5 p.m., this class will help your child treat others with respect and consideration while improving self-confidence -- and to a teenager, that's an enchanting prospect.
