Yes, I know it's a ball.
But it's not the one I want.
I happen to know for a fact that the one I do want
is in your pocket.
No, I am not prepared to make do with this one.
And no, I am not being fussy, I am being selective.
There IS a difference you know.
Or perhaps you don't.
That would explain your inability to tell the difference between
good tennis balls and bad ones ....
