when she starts that yawning
you know you should be going
                  the writing is on the wall
and you can forget about getting another call

when he keeps looking at his wrist watch
you know there'll never be a cuddly touch
                  the signs are there looming large
and dead is your dream about floating on a barge

when the wild party is finally done and over
and the lights start blinking you find you've lost your lover
                                            it's plain to all and sundry
there's no capital in being solitary and sultry

since none of that can change the law of diminishing returns
though some along life's highways may wish for extensions
                                   but passing time means general depletion
and when your back and your eyes start failing it's check-out time
