As a youngster I hated the 1st April. I always seemed to be the butt of the jokes. In a way it made me popular, but I was very uncomfortable with it. The origins of this day where practical jokes and pranks are played on the unsuspecting are not clear. One thought is that it started when the Georgian calendar was introduced and as some people were not aware of it they were recording the wrong date.
As I do every year, I shall try to avoid other people until 12 o clock. Not a difficult thing to do this year! (Can this whole virus be a practical joke?)
