My sisters and I have discovered the power of red hats---you can do whatever you want to do, no matter how silly! The maturity gained through the years disappears in about ten seconds.
As Jenny Joseph said so well:
I shall sit down on the pavement when I'm tired
And gobble up samples in shops and press alarm bells
And run my stick along the public railings
And make up for the sobriety of my youth.
By the way, I'm the one in the red hat.
