It all seems so clear in the cinema. All it takes is passion and dedication,  and you can free the slaves. You can change the world. You can make your life into a burning torch which sets the world alight.

But I get out of the cinema and time is no longer compressed. It passes with all the boring bits left in. The conversations we have to have about what groceries need buying. And the reality: I am not William Wilberforce. I am a librarian with a job to go to in the morning and dishes to be washed.
