[Tango-L] Dividing Tango

[Mario]

I was at a Milonga last week and following the line of dance.
  A couple in front of me were doing 'Nuevo' and the woman was
  swinging gold stiletto heels in wide swaths that seemed to be
  at chin height. I was feeling like the moving of my partner towards
  that whirling fan of heels was like moving her towards certain injury.'
  What the hell was I to do?  So, I paused and they inched away but
  really not enough nor at any predictable rate that I could safely follow
  behind.  Is this something new that is happening on Tango floors?
  Is this going to be the 'way it is', in the future? Should I worry about this?
