A Guitar happened to be there
Everyday at around lunch I take a 30-minute guitar break in the side/meeting/break room attached to our lab. Thank the gods, the old and the new, that there is a guitar there. I really need it.
As is prone to happen in a perpetually-air-conditioned environment and due to daily use, the guitar was out of tune today. Additionally, today was just one of those days when my fingers would rather make mistakes then play the right notes and chords.
A guitar that is out of tune isn't the most deplorable thing in the world. It is still trying to emit the sounds the player is ordering it to emit, albeit slightly badly.
