@roger,
Well, Rog, one certainly does NOT want to ask any "dumb questions" or we may end up like Emily Dickinson and her feelings about The Snake.
note the zero part.
Snake
by Emily Dickinson
A narrow fellow in the grass
Occasionally rides;
You may have met him, -did you not?
His notice sudden is.
The grass divides as with a comb,
A spotted shaft is seen;
And then it closes at your feet
And opens further on.
He likes a boggy acre,
A floor too cool for corn.
Yet when a child, and barefoot,
I more than once, at morn,
Have passed, I thought, a whip-lash
Unbraiding in the sun, -
When, stooping to secure it,
It wrinkled, and was gone.
Several of nature's people
I know, and they know me;
I feel for them a transport
Of cordiality;
But never met this fellow,
Attended or alone,
Without a tighter breathing,
And zero at the bone.
