W: Dr. Jones, how exactly would you define eccentricity?
M: Well, we all have our own particular habits which others find irritating or amusing, but an eccentric is someone who behaves in a totally different manner from those in the society in which he lives.
W: When you talk about eccentricity, are you referring mainly to matters of appearance?
M: Not specifically, no. There are many other ways in which eccentricity is displayed. For instance, some individuals like to leave their marks on this earth with strange buildings. Others have the craziest desires which influence their whole way of life.
W: Can you give me an example?
M: Certainly. One that immediately springs to mind was a Victorian surgeon by the name of Buckland. Being a great animal lover he used to share his house openly with the strangest creatures, including snakes, bears, rats, monkeys and eagles.
W: That must have been quite dangerous at times. Does one of these stand out in your mind at all?
M: Yes, I suppose this century has produced one of the most famous ones: the American billionaire, Howard Hughes.
W: But he wasn’t a recluse all his life, was he?
M: That’s correct. In fact, he was just the opposite in his younger days. He was a rich young man who loved the Hollywood society of his day. But he began to disappear for long periods when he grew tired of high living. Finally, nobody was allowed to touch his food and he would wrap his hand in a tissue before picking anything up. He didn’t even allow a barber to go near him too often and his hair and beard grew down to his waist.
W: Did he live completely alone?
M: No, that was the strangest thing. He always stayed in luxury hotels with a group of servants to take care of him. He used to spend his days locked up in a penthouse suit watching adventure films over and over again and often eating nothing but ice cream and chocolate bars.
W: It sounds a very sad story.
M: It does. But, as you said earlier, life would be the same without characters like him, wouldn’t it?
