I have two acoustic guitars and neither of them has the right number of strings. I lack a particular plastic piece that will help me to change them. I ride my ratty bike the two kilometres to the fanciest music store on Bloor Street – maybe the fanciest in the city – and traipse through the three floors of music stuff to find, finally, the string winder I seek. Alas it’s $19.99, so I won’t be stopping for lunch afterward. The ride home is bumpy and I’m keenly aware that my pocket is $20+ dollars lighter, but the winder is in there, and when I get home, I change the strings on both guitars, then play until the sun sets.
