WASHOE AND THE PUZZLES
I felt really tired when I took the train to work yesterday because Sarah and I had been to a party the evening before. We hadn't gone to bed until after one. I hadn't been on the train long when I had a bit of a shock. I suddenly realized that I'd left my wallet at home. Then I began to wonder. Had I left it in the office the day before? I just couldn't remember. I wanted to go back to bed. I felt awful.
