I concur with Starsky! I personally wouldn'y even get a card, but that is just me...My wife sent a quick text on my Birthday that said "Happy Birthday". Hurt a bit due to us being together for so long, and the fact that she always gone out of her way to do things for all of us on special occasions. But such is life!
I sent her a quick text depicting the same thing a week later for her Birthday. Not sure she was so concerned about any of it, but that would be that "analyzing" thing that Starsky tells us not to do
