answer:This one is interesting. If you had asked for teens in general, I’d suggest Etiquette Grrls’ Things You Need To Be Told and More Things You Need To Be Told, both of which have nice sections specifically directed to boys, and their advice on cellular phone use is priceless, even though the books are somewhat dated at this point (the first references use of pagers, specifically that one shouldn’t carry them unless they are a Doctor On Call or on a Transplant List)
