Book excerpt: REVISED AND UPDATED 2011 EDITION The essence of adolescence hasn't changed since this book was first published in 2005. Their brains haven't skipped a growth spurt; their search for identity hasn't been called off or even detoured; they haven't forgotten how to speak with the ease of attitude. And yet, fingers fly across keys to a host of new adolescent domains--from texting to iTunes, from chats to anything-on-demand. This update traverses new adolescent territory, both charted and uncharted, to bring parents up-to-speed on what to expect and how to deal. Every teenager keeps secrets, and if you're like most parents, you worry about what your kids don't tell you--especially when they prefer text messages and social networking sites to face-to-face conversation. Now this popular guide has been revised and updated to address the challenges parents face with a wired and Web-savvy generation. Jenifer Lippincott and Robin Deutsch offer a deceptively simple plan for talking to your kids that's based on a simple set of rules: Teens need to stay safe, show respect, and keep in touch--online, and in real life.
