*Dance as no one is watching!* has been going around at net as a mantra for spiritual dancing.
I would like to change it a little bit: Check every now and then who is watching your dance!
I learned to monitor the onlookers because I needed to know who among the followers could accept an invitation from a woman leader. A smiling face or an eye steadily staying in contact was quite sure signs of interest for a tanda with me.
Today I appreciate also the eye contact with the leaders because it creates a nice atmosphere on the pista. A friendly eye on my feet during a fierce milonga can give me a feeling of being on the right road and I can happily continue to develop in that direction.
