XV.

Goodbye is an even word.
Three consonants, three vowels, and one that can go either way.
It shows all the symptoms of a word that I'm hard-pressed to say.
Goodbye is not a rhythmic word.
What with it's soft O's and hard Y.
It's the word I find accompanying me in fateful times of deceit and lies.
Goodbye is a hard word.
Two syllables, seven letters.
Due to it's indifference it has potential to make everything or nothing all better.
