Martin Luther King We’d like you to try another thought experiment. It’s in two parts. In the first part you will finally meet the Ruby who gave this book its title. Imagine you are the head of a secondary school and you are walking down the street when you are stopped by an ex-student who left about two years ago. Ruby says she just wants to thank you for the great education she got at your school. You remember Ruby well, so you recall that she left at 16 with two rather poor GCSEs (a D in drama and an E in English). So you scratch around for a response. (You can tell she is being sincere.) You say, “Ah yes, I remember you had a big part in the really successful performance of The Crucible, didn’t you? And I know you made some great friendships.” “True,” says Ruby, “but that’s not what I’m talking about. I’m talking about the quality of the education you gave me. It was wonderful. Really.” And now you are rather flummoxed, and you say, “Sorry, Ruby, I don’t understand what you mean.”
