What a difference it makes being a parent rather than the teacher! I had to step into a completely different role (whilst still keeping an eye on my original part...once a teacher, always a teacher).
Sure, these were French children, speaking French and on a school trip in France, but it was surprising (or perhaps not), just how similar the approach was. It was very reassuring.
I coped quite well and managed to keep all those under my responsibility in line. They must have understood my French.
