People watching is at its zenith in Paris and especially in this well-loved and highly used garden! You can see all types of activities.
On this particular day there was a merry band of people working with movement and large blue fans. Does this have a name? I’m sure it does, but I am ignorant. Post script: Tai chi, I am told. Thanks, Michael9!
get back, lauretta! 
Tai Chi.
It always looks so elegant.
I agree! Would like to study it!
An example of small-townism: a class started my way. I went along. It was soon made clear I wasn’t wanted amongst the middle-age only women group.
How closed-minded the group was! I’m disappointed in them.
