You look for your Mr/Miss Right.
You look left, right and center.
The right person is nowhere to be found.
But you won't take no for an answer. No, sir.
So you find someone anyway who you think is right.
And sadly and without fail, he/she always turns out to be Mr/Miss Wrong.
We all know the story too well. That "you" turns out to be you, I, and everybody else.
