I cycle along the river every day and often saw the same old man with a long beard walking in the other direction with plastic bags in hand and baggy old jeans two sizes too big held up with an old belt. Then for a month or so I stopped seeing him and wondered if anything had happened to him and I regretted not talking to him or asking for a photo. It just so happened that he was there this morning, so I stopped for a chat. It turned out that he is homeless and lives in the forest and makes a long walk every day into town. He was very polite and spoke English in quite a posh clear accent so I wonder what happened to him in his life. I asked for a photo and he declined. Sometimes I would feel detected but in his case I was just glad he was OK.
