A stranger tuned my ukulele and now we play every Friday

On a Friday at 4pm I was on a bench in San Pancho practising the same four chords when a man sat down and politely told me I was one note off. He took the ukulele, fixed it in three seconds, and gave it back. We have played together every Friday since. I am still bad, but now I am bad in tune, and I have a friend who says my playing sounds like a short walk. He is right. It sounds like a short walk to a place you have already been.
