Debrett's, the publisher of the decades-old high-society etiquette book "Debrett's Correct Form," has come out with a new book on manners for the modern girl. "Etiquette for Girls" catches up with the times, but still insists there is "proper" behavior for young ladies of the 21st-century. There are, for instance, correct and incorrect ways to conduct an office fling, have an affair or gossip about celebrities.

Jo Aitchison, the book's editor, tells Reuters, "It's a nod to the modern day. We're pulling Debrett's out of Victorian times and trying to make it relevant to today."

While "Debrett's Correct Form" provided guidance to those who desired to write faultless letter headings or arrange dinner-party seating according to social hierarchy, "Etiquette for Girls" gives advice like this:

"Avoid dark-alley gropery and unladylike fumbling in the back of a cab. Discuss the necessaries to avoid planting any love children or disease."

Other topics the book touches on are how to smoke properly, how to behave on the way to work and what to take to a music festival.

Aitchison says, "We are trying to give girls confidence to behave in the correct way. It's a bit like a survival guide for modern life, so we have had to include certain subject matters that are new for Debrett's."
