When the oxalis sleeps

These beautiful leaves close each evening. The plant is very temperamental, lying down dramatically if not watered enough, rushing into growth if conditions are good. I have friends & grandkids like this.
Up to see the grandchildren this pm. K. full of energy, scootered home from school with M in hot pursuit, then swapped to roller blades & had me as escort while M dealt with F on kamikaze skateboard.
