You got your write mirror image to righties only in the other direction lefties and your hook your arm around and write from above lefties and apparently the right/left brain handling of language is different in the two groups.

I have heard that - although some left-handed guitarists just learned to play/approach the instrument by *flipping a 'right-hand strung' instrument over (making the lower notes nearer to the floor) some prefer the guitar to be 'left-hand strung', as a mirror image.

Parbably the same *issues.
