I was on a blind date with a young woman many years ago.

She asked me to meet her at ‘the big oak tree’ in a familiar area of town.

There was no oak tree there. When I got there, after wandering around a bit, I found her sitting under a giant pine. I said ‘Hey, this isn’t an oak tree.’ She said, ‘Yes it is.’

The date went on. I bought lunch.

At one point I was trying to explain that I was a little different from the people she probably knows. She said ‘What do you mean?’ I said that I am the sort of person who feels that if any person is in prison, part of me is in prison with them.

She looked at me funny and said she felt sick.

I am glad she said that, because trying so attentively to relate with someone who has confused a lego brick with their mind was making me feel weird too.

At the end, I got the joke: it was a blind date.

Her eyes worked fine.

Mind? Completely blind.
