Awesome reply. Even though I'm the guy who keeps the 'good' towels aside for when company comes over while using the old rags for myself lol, I share your sentiment with musical instruments.
The only thing I will never do to it is deliberately abuse it, or allow myself to 'unconsciously' damage it. For example, I just don't grasp how belt buckle rash appears on a guitar - especially a $3000 PRS. It is SOOOO easy to shift the belt buckle over on your hip so you don't damage the guitar....
Which of course I forgot to do today when playing the new guitar. Until I heard a "clunk." Fortunately, no damage at all.
Still, I was a little angry at myself.
