An excerpt:
  "I recommend  contradance for clients who want to
do something fun  
 that doesn't involved drinking. I send people who have enough  
 attachability to tolerate the eye/human contact and who can  
 tolerate some positive affect. If your person has an anxiety  
 disorder or very low self-esteem, they may not tolerate the  
 learning curve. I suggest these people get a few lessons before  
 they hit the dance floor. I warn other clients that they will be  
 completely lost for the first few dances, and then they'll catch  
 on. They do, and come back triumphant. You may want to try it  
 yourself, before you refer your clients. But only if you want more  
 contact, more community, and more joy."
