Asking for "one" dance

Have danced with three more teachers, one Argentinian guest teacher, and two local ones. Two of the three knew me from their classes and one (local) didn't know me at all.

In all cases the dance seemed to flow very well, but I kept it fairly simple to be on the "safe" side. The general feeling I get is that it's better to keep it simple, but stable and secure, than to try fancy moves that have the possibility of throwing me off my posture and them off their balance. I've also been specifically asking for "one dance". My thinking is that they would be more inclined to say "yes". In two cases they "asked me" for one more... and that felt good.

My partner commented that in line with my "owning the dance" I should just ask them to dance and let them "thank me" if they don't want to finish the tanda. At this point I feel it's really easier on myself to approach them from the point of view of an advanced student who would like to "experience" dancing with them ... than that of a tanguero who is offering them a dance they will enjoy... but that's not "owning the dance" is it? So, she's probably right. I'll get there.
