Do we know what time his train arrived in London or what the time was when he was seen on CCTV? When I was young I used to just pop into London for the freedom, to gather my thoughts, to people watch, to feel anonymous, to do something for the day without anyone knowing, the thrill of feeling slightly more grown up. Perhaps his visit to London was just that, maybe there wasn’t a specific reason. Maybe he thought once he was there and tired of this freedom he could just buy a ticket to go back home that very same day but obviously he never got back home. I’m not sure how long the trains took back then but maybe he thought he could be there and back before his parents noticed anything. The uniform left at home could be used as an excuse if he was late back that he had gone back out after school for whatever reason and that was all, hiding a much greater adventure… MOO. Also, I can’t remember what times his parents would have arrived home after work, was it after he had finished school or before?
