Her Majesty's School of Stress Management.

On my window sill in the kitchen stands The Queen. Grey haired, tiara in place, with a fixed smile day and night. You might be surprised that I display something that kitsch there and amused to know that she waves. 
          All day! 
Yes, my Queen is solar powered. On her handbag (purse) is a solar strip, that keeps her going longer than the Ever Ready Bunny. 
And why is she there in perpetuity?
