My favorite Christmas carol this year is The Little Drummer Boy. I think I've known it probably as long as I've known any Christmas song, but this year it just stands out. When you first hear it, it just sounds like one of those repetitive songs that keeps getting stuck in your head, but if you focus on the actual lyrics and not just the "rum pa pum pum," it's actually quite a deep poem with a nice message.
And it makes me cry every time I hear it in the car. One time I had to turn the channel when I heard it, because I was on my way to Ballet club and didn't want to look like I'd just been crying. I already looked like I had just rolled out of bed into my leotard, so I didn't want to add to that.
I just don't cry during the David Bowie/Bing Crosby duet of it, mostly because you can't near the actual song over David Bowie's hippie Christmas lyrics.
