Violin encounter

Let's see if I got this straight: You're supposed to spend years of practice before you subject an audience to your interpretation of squeaky toy improvisation, but when you touch a violin for the first time, you might as well let the world see it, since it's not one of those complicated things that require learning. Right?
My grandmother was well on her way to becoming a concert violinist when she was snatched into matrimony to spend the rest of her life as a pastor's wife raising eight children. She had a perfect ear and high standards regarding music and is probably very angry at me right now. Sorry, mummu! May you rest in peace. I will not mess with your violin again.
