That's a lovely story Pom Pax. That CC needs a reward for entering into the spirit of the journey.
I always take a walk on lonh haul - even if I'm in Y I walk to the front of the cabin and back. When further up, I walk to the back around 'the bend' and back up the other aisle several times in the flight. Often you meet other pax for a chat, or CC who ask if you want anything to drink and mebbe have a chat with them too. Some of the best moments in long haul are those walks and chats.
