Do you identify a tree as a tree? Or do you identify it as a cloud?

Do you look up at the clouds and call them grass? Or do you look down at the grass and call it water?

Simple basic perceptions.

Not between colour blind people.
Not between people who want to be different and break the norm.
Not between two stoners who are stoned and want to be funny.

Between your average day Mr. and Mrs. Joe.
