I'm so glad I have friends who understand - things didn't go according to plan. First of all the play was due to finish 10 minutes after the last train left for Coventry. I worked out an alternative plan where A got the train to Nuneaton and caught a bus back from there. A was feeling uneasy about getting from the train station to the bus station in just 15 minutes so he decided he was going to leave the play in the interval and get the last train straight home. I went with him to the train station and he got in the queue to buy his tickets, but the people in front of him were taking ages. I could see he was agitated but he was insistent he wanted to buy the tickets himself. Unfortunately the train left when he was in the queue which tipped him over the edge, he was getting so close to a meltdown I told him to go outside and calm down, I would get the tickets for him. I was so upset at this point I bought tickets for Nuneaton instead of Leicester! He said it was a waste of time going there so we ended up just going home, he's only calmed down by playing on Minecraft
