My dad used to send me cards and little gifts for Valentines Day. I think he loved it too. I sent him flowers a few times and he used to tell me that flowers aren't just for girls.
I go for all the mushy stuff: the cards, the chocolates in a heart-shaped box, the red flowers and teddy bears. It seemed a lot easier when I was 1) back in the States and B) younger and dumber. When I was engaged (waaaaaaaaaaaaaay back before the invention of fire), my x-fiance used to get me Godiva chocolates in a box and little gifts (diamond ear rings one year - kind of a big thing!). I was SO spoiled and SO clueless. I just didn't know what I had. (Not that I wanted him and THANK GOD I didn't marry him.) It was nice to be treated so well and to feel so loved and cared for; even though it has taken me a while to figure out how really special it all was. (I was somewhat of a mean girl.)
Of course, he might have been doing all that just to get in my pants, come to think of it.... But still.
