Mabel Watson Payne on a rainy Friday afternoon, holding the olden-days blue plastic CD-player I use (while commuting on MUNI) for listening to opera with my treasured Bose headphones (which nevertheless Mabel is of course welcome to play with absolutely anytime). She was curious about how all the pieces fitted together and how the sound came through the headphones right into her ears. But she asked me to turn the volume down almost to a whisper, otherwise it seemed too loud to her.
