... this friendly and helpful lady manning the tourist information counter. Not well-versed in English at all, but tried her best to provide me direction to nearby flower park. When we returned to the station, she approached us with a book in her hands, pointing to one of the English phrases in the book, "Hope to see you again!". She tried to learn the pronunciation from us and repeated after us. Before we board the train, she passed us stalks of fresh lavender flowers as a momento. Will never forget the cheerfulness she portrayed and assistance rendered despite the language barrier!
