I work in a hospital. In the main corridor there is a series of large portraits of not only great doctors but great thinkers. Like Alberts Sweitzer and Einstein. One portrait is of an elderly Helen Keller and her elderly companion Polly Thompson (the only “double” portrait in the corridor). As I was walking by just now a woman stopped to look at it, and said to her friend “Wow, this is a great one! Come here, you have to see this!”
So the friend looked at it and said “Wow, that is great. But how come there’s two of her? Oh wait, I get it. In one she’s not wearing her glasses.”
Yeah, I know. If I’d never gone to college with Helen Keller and her twin sister Helen, both of didn’t wear each other’s glasses, I never woulda spent that year at I-Hop.
… which really made things hard on their sister Lauren, who was constantly going through life introducing them: “Hi, I’m Lauren, this is my sister Helen, and this is my other sister Helen.”
