Too close for comfort

"Be wise, be smart, behave, my heart
Don’t upset your cart when he’s so close
Be soft, be sweet, but be discreet
Don’t go off your feet, he’s to close for comfort

Too close, too close for comfort, no, not again
Too close, too close to know just when to say "when"

Be firm, be fair, be sure, beware
On your guard, take care, while there’s such temptation

One thing leads to another
Too late to run for cover
He’s much too close for comfort"
