A guy approached me and asked me whether I'd accompany him and he'd pay me in exchange for taking some pictures. I said no thanks. He continued and said, "Of course, I'm not talking about just any photographs; after all, that's what I'd pay you for." I still declined, and felt glad that I had done so the first time as well. Even though I didn't have any idea back then of the full impact of the request, it felt a bit weird to be asked for photographs by a stranger.
