A friend lent me this book. I had never heard of the "Five Love Languages". It was interesting to read that everyone needs different kinds of affection. Even though you know this, it's very good to read about it in-depth.
Especially teenagers need a very different approach as anyone else. As a mother of two teenagers and a teacher at church, I know quite a few and have always found it better to approach them the way they approach you (though not as moody, hopefully).
This book has given me a much better insight and a lot of helpful hints on how to deal with people who are in their most difficult stage of their lives - somewhere between childhood and adulthood, not yet having left the former totally and not entirely joined the latter, either.
I would recommend this book to any parents of teenagers.
