What is your most memorable in-flight experience on a 10+ hour flight?

Flying with Thai Airlines, London to Bangkok for our eldest daughter’s funeral. The crew had no idea why we were flying, but they noticed my Mrs was crying every few minutes. On a trip to the WC I asked a crew member for water for my Mrs. They asked if there was anything they could do to help. I informed them of the reason for our journey. 20 mins later we were asked to move ……………… to business class as there was plenty of space and it would be a little bit more “private”. They even bought our carry-on luggage upstairs for us (Airbus A380) The crew was empathetic, attentive but not intrusive. The best got better.
