Question

How does one differentiate between a fact and a wish?

Answer 1

Well, I have heard of a fact or fiction.

I guess I would compare a wish to a dream. I try to rhyme;

Many dreams may never come true,

But, now and then some do,

If, I were to wish upon a star,

it only a wish as it has not come true,

But, when that wish is reality,

Then a fact it will be!

So;

A wish/dream may never come true,

but, from above sometimes they do.

Without the dream life becomes a bore.

When the dream comes true, we desire more!

Answer 2

Facts:

You will die

You will have to pay taxes

Wish:

Everything else.
