I read it when I was at school 14-15 years old, but that was a long time ago, so I had forgotten most of the plot. I don't recall ever having seen it performed on stage, so what I did recall were mostly isolated quotations out of context, forgetting who had said them, things like "Rich gifts wax poor when givers prove unkind", or "a little more than kin, and less than kind". So it was good to re-read it and put it all back together again.
