His option to relax is to invite a less demanding partner and after a really bad day maybe a beginner is best!
It depends on the dancer!
For a variety of reasons, 2022 was a bad year, the entire period from 2016 to present hasn't been great, and I felt everything weighing on me yesterday. Consequently, I was tired on every level at the milonga last night. The place was unusually crowded, too. I danced with 10-11 partners of varying skill.
The beginner and near-beginner partners weren't relaxing to dance with. I had to devote my mental and physical resources to protecting them (and people near them . . .) on a packed floor, to compensating for their posture, to generating more than 50% of our couple's energy, and to
not dancing my full range of movements or the music's full texture (constantly checking myself to avoid anything demanding from
them is demanding for
me). I was extra-tired after those tandas.
My most advanced partner normally accepts invitations only from teachers and visiting performers, but she asked me to dance. Our tanda was zero work. Everywhere I turned, she was squarely in front of me. She projected into every step and transferred with a clear, "I have landed." When air was open in corners, boleos went precisely where I pointed them. All of her movements were informed by the music, and it felt like I had hours between notes for my ornaments. I could dance without thinking and was relaxed, and at the end she said, "Wow, you're fun!".
My experience is that the lower a dancer's level, the more demanding they are, because I'm compensating for their limited technique, floor awareness, and musicality. The higher their level, the more evenly we can share all parts of the dance 50/50, which is where I dance most effortlessly and with the greatest pleasure.
To be clear, if someone is super-advanced and compensating for me, it isn't relaxing either. I
know when it's happening and I feel intimidated by such an advanced partner, disappointed that I can't give them a better tanda, and guilty that I'm making them work . . . because were the roles reversed, I know I'd be working.
So, I question non-beginner leaders who invite beginner followers with the claim, "It's easier!", or, "It's less demanding!" Ease and effortlessness are at their highest levels when the partners' levels are equal or very close. My impression is that non-beginner leaders invite beginner followers for social reasons: Maybe to welcome and encourage them, which is inclusive and a good thing – but in my experience, all too often to try to impress them, which strikes me as very macho.
