My daughter Andie was a southpaw and kept taking my guitar and trying to play it upside down. It was painful to watch.   Oddly enough she was figuring out how to make chords upside down and that was no mean feat because she had the shortest little fingers.

I ended up restringing it and giving it to her, just before I moved to UK.

Needless to say... if someone wants to play badly enough they will find a way.

That didn't sound right... play badly. Need to stop now.
