Compact Pact

What I am writing about, is a simple four letter word It's a word that's rarely used, in life or in daily homes The reasoning behind this word, is too never to let it roam This word that I've been invited to write about It's so invisible that we rarely do see But this word so resonates, in peripheral, it surrounds thee Please now open ones eyes, be compact and tell For the word I describe is pact, used correctly, this word works well *~*
