I think you should just let him know how much it means to you, and how much it helps the school for his honesty. HTH

Recently our treasure lost the PTO check book and it was found by a young man and returned to the school. The board relizes how tragic this mistake could have been had the check book been found by someone less honest. We feel we should aknowledge this good deed. I have been tring to write a thank you note but I'm not having any success. Help please. Thank You
