If I were to start referring to apples as, say, "oranges", instead, would I have any right to say someone was "wrong" if they were to call one an "apple"? As many before me have said, it is all a matter of perspective. If a sentence in a book said, "The grass was bloodstained red," the author would be pointing out that the grass is differing from green, which, in the author's perspective, is the expected color for grass.
The post was quite enlightening, very informative.
I'm somewhat new to this site, so if I have managed to use any of my words "wrong" by the definitions listed above, inform me, please.
