The FAO had no idea that I had assisted him run.
Would you mind detailing how you had assisted the Glaswegian in this regard?

No, not at all.

The Scot had a very large backpack. The problem was to exit the school without the police office at the gate seeing it. And also to pull the runner on a Saturday morning, so that the Scot's absence wouldn't be noticed for at least another 12 hours or so, until gate curfew, and certainly not before he was airborne on his international flight out of Chengdu. In fact, he was terrified that Sunny would be at the airport to prevent his departure. A phone call from the school to Sunny in Chengdu was almost a given should the school realize what was up.
Getting the huge backpack out of the school was easy. Empty its contents, and fold it. Then put it in a medium-sized hold-all bag that could pass as a shopping bag. Then do some more exits using the same bag to carry his personal belongings. Once everything was at the bus station, re-pack the backpack and place it under lock and key there on Friday evening. On Saturday morning, he departed by bus. The school didn't know about his run until Monday morning when he didn't appear for class. Shortly afterwards, the FAO had unlocked his apartment, which was on campus. As all his stuff had gone, and he was not there either, the penny had dropped in an instant!
