Piano Strings Attached

One of our pianos, our baby grand,  needed a string replaced. The combination of a new piano wrench, an initial wrong threading, and a very dusty piano  meant three hours of work instead of one.  The good news is: Don, our piano tuner, did not charge a penny (he said we were his guinea pigs for his brand-new piano wrench). He did accept a cup of black coffee.  He will be back later to tune the piano.  BTW, how does ONE note with its broken string  result in FOUR, new strings?!
