I received this message last week.  Made my day:

Hi Carl. I’m sure you don’t remember me but you photographed my wedding in 2005. I wanted you to know how much I continue to cherish the photos you captured that day. In particular I have been spending a lot of time looking at this photograph of my grandmother hugging me over the past 24 hours. She passed away on April 28th 7 years ago. It’s difficult to describe the emotions I feel when I look at this photo, but I can tell you that it is without a doubt my favorite image of her at any age. So thank you for this gift you have given me and my family that truly continues to bear fruit regularly to this day. I hope you are well and I wish you all good things!
