September 22 was the Autumnal Equinox, when day and night will be the same length for one strange day, before we slip into that cozy-or-depressing-depending-on-your-perspective darkness of autumn and winter. Every year the equinox inspires a 50/50 night and day of mixed emotions, too. I mean, don't you just love fall, with all its appley-pumpkiny-leafy crispness and opportunities for sweaters? And then there's Halloween, basically the only holiday worth celebrating. And yet there's always that dark, cold, mucky winter-chaser to gulp down afterwards, about which most of us feel less enthusiastic. So what do you do on the equinox? It must be something slightly mysterious, I think, slightly odd, in touch with nature in some askew way. Like, maybe, silent dancing?

Allow me to explain: a friend of mine recently shared this video, AKA the most beautiful, strange, haunting "What I Did On My Summer Vacation" report in the whole land of Facebook. She explained that she was strolling along on a hot summer night in Lisbon when she came across these people silently dancing the tango outside a church. The result is a dreamy spectacle, captured in a hazy camera-phone movie that I've since watched approximately 80,000,000 times, wishing I were one of those dancers. Something about the silence and the darkness make them seem not like individuals but like a force of nature.

So why not dance silent tangos at midnight in the week after this equinox? You don't need a church, just any sacred-ish space will do -- a backyard, or a courtyard, or a roomy fire escape -- and the will to give yourself permission to dance to the moon even when there is no music. Or at least watch this video a few times, while contemplating the mysteries of the universe. Happy Equinox.
