If you have a teenage daughter, you've probably encountered a whole laundry list of issues that you had never even considered. Living in this day and age is difficult enough as an adult, but kids really have it hard. Peer pressure isn't new and, in reality, it hasn't changed a lot over the years. Instead, the issues facing kids today are different; no less difficult, but not nearly the same as what you may have encountered when you were a kid.
The issue of how to deal with a teenager is a story that has been written millions of times. You can find books, articles and seminars that purport to teach you how to deal with the hormone-filled youngster that is living in your home, but nothing aside from living through it (and subsequently dealing with the issues) is going to help.
