“In looking through my files in preparation for filling out my tax forms, I came across a “punch list” from LeeCorp  and realized that I hadn’t thanked you for taking care of all the problems that were on that list.  So, thank you.  Hope all is well with you and yours. I’m sure you are looking forward to winding down a bit since the season is coming to an end.  Or is it?  At any rate, thanks again for all that you have done for us.”
