They like to go round and round and stay snug. They sit quietly and hold your gear in place so you don't have to. It's not a glamorous job, but someone has to do it. They are happy to and be part of your musical adventures. They watch you in awe and might whisper at night about the good times you have. If you take good care of them, they cheer you on and do wonders to your tone.
They are just screws, and they do what they are supposed to.
