What are you reading? Polonius asked.Words, words, words, said Hamlet.And what's the subject?Lesser than the king, but still not nothing.It took Polonius a moment to realize he had answered another meaning of 'subject.' I mean what do you read about?All in a line, back and forth. said Hamlet. I go from left to right with my mind full, and then must drop it there and head back empty-headed to the left side again, and take up another load to carry forward. It's a most tedious job, and when I'm done, there are all the letters where I found them, unchanged despite my having carried them all into my head.
