Dear Richard Anderson,
I thank you with all of my heart for the time you took to talk to our son, Colin, last month. Your words have had an amazing effect on him and he is now a changed man, his anger seems to have totally disappeared. He has returned to being a loving son once again. I do not have enough words to express my gratitude but I pray and give thanks for you everyday.
