That Pesky Spot

You're the unsightly stain on my best tablecloth.
No matter how hard I scrub I can't get you off.
He's coming to dinner and you cannot show.
It's our first date, and he doesn't know.
I do my best to keep you from sight,
with distracting centerpieces and dim candle light.
But when the dishes are cleared, it was all done in vain.
You're in plain view, and I flood with shame.
