Below is a white diamond imported from Africa. . .

Or is it?

It may be cubic zirconia.

You can't tell, and the only difference would be what name I ascribe to it.

The point:
If you look at this object and it is appealing to you, then what difference does it make if it is a diamond or cubic zirconia as long as you were not misled?

The analogy:
I have never met anyone who said, "He was perfect in every way. He was intelligent, articulate, stable, interesting, talented, handsome, loving, funny, and built pretty good. . . but then he told me his age and I dumped him because I don't date people over 30."

Akin to losing a long-time friend because you tell him you're gay.
Odd. . . am I not the same person?

Note: This has never happened to me. I guess I have been fortunate enough to make the right choice in friends over the years.

The Short Version:
Numbers don't matter to me. If you would like to know my age out of sheer curiosity, I will be happy to tell you. If you want to know because it is a deciding factor. . . you needn't bother to ask.
