“Out damned spot!” Thanks to Covid-19 we’ve had more than a year now of compulsive sanitisation – gels, hand washing to the national anthem, masks, Perspex screens and deep cleaned surfaces.

Nobody in their right mind wants to catch the virus.

It was reassuring too, to feel that we were doing what we could to protect to protect ourselves.
