Wow as if you weren't already incredibly beautiful, your talent and intelligence make you a centillion times hotter, and I'm not sure that's mathematically possible.
So... did you just happen to have this costume, and decided to learn the song for it? Or you knew the song already and were just SO COMMITTED to the theme you went out and bought a lumberjack shirt? I'm not complaining: beautiful song. Mysterious/melancholy goes well with Christmas. And you look really cute in green flannel.
