Last night I went to a meeting of the Twinning Society. It was there AGM. I must have lost the plot because I asked a question that had already been answered. A lady across the table, who has a prosthetic arm and hand laughed at me and said "Try and keep up". I was very embarrassed. There was no point in trying to explain and anyway I was not in any fit state to do that. This ladies disability is in clear view to everyone, mine is not. Her remarks were born out of ignorance not malice but it brought into sharp focus how PD can catch you out. I can't get it out of my mind so totally brassed off today.
