As a tourist in London, of course, I went to see some of its hundreds of museums. They taught me a lot about the arts, nature, and human history, but they also made me really sad. We all try to create happy memories, but have you ever thought about how our history is made up almost entirely of sad ones? When we learn about history, we learn about wars, crusades, holocausts, slavery, terrorist attacks, natural disasters, epidemics, sultans murdering their younger siblings to consolidate power, powerful nations imposing their rules on the less powerful.
Changes are not driven by happy people dancing in the village squares. They are driven by people in chains, in pain, in famine. Revolutions are not driven by people who still have a lot to lose. They are driven by people who have lost everything.
