As I sat on the train, heading to a place I had never been before, to mourn the loss of a young woman I had never met before, I looked around. I wondered who else looked like they were making the same journey, on a chilly Friday, to a south-east London vigil for murdered schoolteacher Sabina Nessa, to say her name.
A student in a denim jacket came up to me. Like me, she said she felt scared of walking somewhere new alone. We got off the train at Kidbrooke station, near Blackheath, and ended up walking together, joining the stream of mourners. Many held handmade signs, as candles and floral tributes piled up on every surface.
