acetic

"My thoughts are crabbed and sallow,
My tears like vinegar,
Or the bitter blinking yellow
Of an acetic star.

Tonight the caustic wind, love,
Gossips late and soon,
And I wear the wry-faced pucker of
The sour lemon moon.

While like an early summer plum,
Puny, green, and tart,
Droops upon its wizened stem
My lean, unripened heart."

"Jilted" by Sylvia Plath
