The point I'm try to focus attention on is that there is a chasm between making her feel great and not complaining. Not complaining is easy. Making her feel great is tough and might require acting that goes beyond reality.
If I give my partner the idea that the dance was great..
It seems there is still some confusion about whether the dance has to be great for people to feel good at the end of the tanda. The dancing can be a disaster, but approached with a sense of humor and generosity, it doesn't have to be a bad experience.
Haven't you ever laughed with the other person about a fooba that occurred? I've seen people actually go down in a heap and be able to laugh about it or joke later about it... what could possibly be more of a disaster during a tanda than falling on the floor? (well, not counting making some other couple hit the floor!)
Also, there are more ways to be "complaining" than just verbally. And more ways to express dissatisfaction than just verbally.
I think if a world famous leader can dance with a much lower level dancer and leave her feeling good, it's pretty clear that the attitude and the assessment of the partner's dancing or the relative "greatness" of the dance itself don't have to be tied together.
Every time we mention something about making the partner feel good (or at least not making her feel bad) someone mentions that if the dance isn't good, then he'll have to pretend or act. That tells me that people are still determining whether or not they had a good time and whether they help the other person have a good time based primarily on the quality of one or both person's dancing.
What I have been trying to say ad nauseum, that either is not getting through or there's just too much resistance to the whole concept of responsibility for one's own attitude, is that, again:
The dance doesn't have to be wonderful for the experience to be wonderful
I've said this over and over using way too many words, and frankly, I give up.
