The most infamous person I ever met – by accidental association – was a very drunk man in a very unhygienic cafe – there were flies everywhere – when I was a very, very little boy.

His wavering walk, his unkemptnessq and his face remain embedded in my memory some 73 years later.

He lurched up to the table where I was sitting with my parents. He interspersed several lines of “Silent Night” with the words “Why worry” over and over and over again.

That engagement frightened me to my innermost core. The experience is one I have never forgotten.
