You can also find it on Ao3 or FF.net
Also, just to cover my bases, I'll include my author's note. "Back in 2011 or 2012, when I was reading pretty much every fanfic ever written, I found a lovely story called Mistletoe Woes by an author named lifeistoobrevis on Livejournal. I don't remember details, but I remember the premise being that Daniel wouldn't kiss Vala under the mistletoe. He was willing to kiss a nurse though, because it "didn't mean anything."
That story and indeed the author's entire LJ account has since been deleted and purged. I wanted to reread it, because I remember liking it, but it's gone.
This is not an attempt to recreate that story-merely my take on that idea. However, if the author of the original happens to stumble across this and declares it too similar to his/her work, I will of course take this down."
