• To help with those long hours of hitting the books, provide fun study breaks (a game of Scrabble, one half-hour sitcom viewed together) and energy-boosting snacks (lots of fruit and drinks).
• If she starts hanging out with boys but insists that they're "just friends," give her the benefit of the doubt. It's true that boys and girls spend much more platonic time together at this stage in their lives than they do others; constant teasing and speculation ("Your boyfriend's on the phone") will just embarrass and anger her.
• To let him know that you value his personal space, suggest that he and a friend paint his room and use any colors he chooses. It could probably use a fresh coat anyway, and why not let him express his individuality and creativity in a harmless (possibly even beautiful) way?
• Keep your sense of humor. Teenagers can actually be quite funny if you let them. By demonstrating your own skill with witty repartee and love of a good guffaw, you'll help keep things light and fun around the house.
• Live your values. If you want her to accept your own morality and way of looking at things, be prepared to practice what you preach. You'll feel more justified when handing down pronouncements for infractions such as lying or smoking, and she'll see right through you if you don't.
