"Greg, I still can't believe how you came to the rescue of this old lady and then how kind when the best of all engineers told me that he was not going to charge me.  There is no end to my gratitude to you Greg and how very kind and considerate of you to grant me your talent, free.  I have missed not seeing you all of these years and I am glad that it happened as now I will be able to see you periodically.  It was so good to talk to you again as it was just like old times, with the exception that I am falling apart.  Thank you from the bottom of my heart for being such a wonderful, benevolent person to do this for me."
