Dancers?

The extra gives the explanation. 
Green Gym at Discovery Centre today.  I was planting bulbs (Gladioli) and sprinkling wildflower seeds.
Bom and GracieG dropped by but only to take pictures and not to work!

Maths group this afternoon.  Couldn't get my head round Quadratic equations, didn't remember them from school at all.  Just as well I don't need them to enhance my life.
