John and Jan,
Jennifer and I are very sorry to hear of the passing of your son Mark. I liked Mark very much. He was a fine young man, always very happy when I saw him. He will be sorely missed.
Our sincere thoughts and prayers are with you.
I would like to send my heartfelt condolences to John,Jan,Derek and the entire Greedy family. I'm sure Mark will be deeply missed and you will keep a warm place in your heart for him. May he rest in peace.
