"first christmas"

Today, on the eve of Christmas, we received about a dozen holiday cards. Each card from close family and friends, it was lovely. However all but one of our cards wished us a happy "first Christmas" together. Um, this is actually our SEVENTH Christmas together. Do the other six not count because we weren't married. What if we were engaged to be married for two of those six? Do they count? WTF people? I am not sure why this annoys me as much as it does. Maybe it's the vat of Asti I've taken down single handedly today. But it ires me and so I am venting about it on here. Happy SEVENTH Christmas Joe and Niki. It's going to be a doozy :)
