In searching the night for the "perfect dance partner," I prefer a different frame of mind--how about, "all of the dances are going to be wonderful! Who do I get to dance with first?"
Armed with an open mind and spirit, my dances come across as an invitation to other rather than imposing an expectation.
The next time you go out to a dance, try thinking of the evening as a celebration. If you are alone, just think about all the others who are there alone who would appreciate a smile or a kind word from someone as wonderful as you. Raise a glass and have a dance!
