Dear Mr Dawkins.
I'm 17 years old and was 15 when i first discovered 'The God Delusion'. I just wanted to say thank you for changing my life. I've read it 3 times and to this day it is still my favorite book and probably always will be! Since reading it I've looked at life differently. I've recommended the book to all my friends and they have all thanked me too! I love what you are doing for evolutionism and atheism and when i grow up i also want to help further both causes. We need more people in the world like you, people who only try to inspire and teach others. So please always continue doing what you are doing and never listen to the people who are too in denial to appreciate the marvelous work you are doing.
Thank you, always. Sean.
