Rumba and Waltz

I took up ballroom dancing (cha-cha and rumba) with a partner a few months ago, and despite a little unevenness in scheduling I had a wonderful time. It was interesting to see that it was very common to see men without partners at the lessons week after week - or maybe I just knew about them because I switched off now and again. I wonder if I could muster the courage to go without a steady partner - it being such an old-world activity, the old-world prejudices aren't far behind, though I would be in the running for the youngest spinster in the room. I do so love waltz music.
