Show Your Pearly Whites

They say your teeth are nice.
I'm surprised you didn't reply
"The better to speak false promises, my dear.
The better to deceive you, my love."
Instead you replied with a benign
"Thank you" followed by a modest "Braces."
And where this bitterness comes from
I have no idea.
I was not aware I had anything against you.
At this point anyway.
Normally my bitterness warns me beforehand.
My words similar to coffee.
But no, I do not have a fixation.
A warning like my eyes give me
Before I drink the dregs of unwanted coffee grounds
Found in my coffee cup.
My feelings like grounds.
Surprising and misplaced.
