That is lovely, I thought it must be appreciated but so many men never let on.
My stepfather's son never bothers to contact him, which makes him very sad, and he has a young GS who he only saw a few times before his DS and his GF split up. When my mother remarried I started to send him cards. Two of my sisters weren't all that keen on him, but he is a lovely man, and I felt sorry for him as my mother was always saying that his son never bothered to send him anything, ever. My sisters were really annoyed with me, saying, he isn't our father. But he's the nearest thing I have to one, and as my mother can be very awkward I am eternally grateful to him for keeping her off my back! I received a lovely thank you for the card, saying that 'you have no idea how much I appreciate your thoughtfulness'. So, Hallmark day or not, it's not being forgotten that counts.
