Speaking of devolution, you may or may not be aware but by flopping the negative you have also messed with the sexuality of the person's involved.
A lefty is now a righty ( and I'm not talking handed).
The sexuality is called into question as the shirts and jackets are now buttoned on the wrong side.
Due to the depth of field the people in the back may not be affected, but sure as hell you just made that poor boy gay.
Or at the very least a cross dresser.
Actions have consequences.
