John Horgan’s meeting with a modern-day Good Samaritan leaves me humbled. I spend too much of my weekend driving children from A to B and back to A for no benefit to myself apart from my relief that they want to go somewhere, anywhere. But to help out a complete stranger in this way? I fear I would not be so heroic. I have certainly missed my stop in the same way as John Horgan before now, though — most usually by being absorbed in a book. It is easier to do on the Underground than on the regular train, I find.
