I have always been quite bad at recognising people I have met just briefly. As a young art student I was making costumes for an amateur theatre. The upcoming play was Dracula, where one of the characters is taken to asylym. I was in a process of sewing a strait jacket for the actor of this character. One day I was sitting on a table in the art school canteen and saw the actor walk past. I yelled to him: “Your strait jacket is almost ready!”. The man stopped, looked at me perplexed and asked: “what did you say?”
Of course it was a wrong person. The one in the canteen was also an actor, looking like the one who was acting in Dracula, but totally ignorant that somebody could be sewing him a strait jacket.
