Is there a standard convention for using right and left when describing a person? Should it always be from the perspective of the person being described?
For example, when describing a flat object:
There was a ketchup stain on the right side of the painting.
This sentence is using "right side" from the perspective of someone looking at the painting.
For non-flat objects:
There was a bright, hot-pink streak on the right side of the car.
This is strange to me. It could go either way, since the car has a "front" and "back", it also has a "left" and "right", so the hot-pink streak could be on the right side from the car's perspective, or the right side from the viewers perspective.
The same applies to people:
He was an older man with a huge, curved scar dominating the right side of his face.
Does this mean that, from his perspective, the scar is on his right side, or his left side?
