Thank you for holding a banana leaf over my head in the rain near Sayan

On a back road near Sayan on Wednesday afternoon the rain was the kind that goes through a shirt in three seconds, and a woman on a scooter stopped, pulled a banana leaf out of the basket behind her and held it over my head for the fifty meters to the next shelter. She laughed the whole way. So did I. At the shelter she handed me the leaf, said, keep, and rode off in the rain, which she did not seem to notice. I still have the leaf. It has gone brown. I have not decided what it is for.
