Simple word.
Four letters, two consonants, two vowels, one of them silent.
Home.
I wish I could walk through a familiar door, shout out the words in a simple two-word sentence: "I'm home!" But that door has been closed to me, slammed shut in my face, and no amount of pleading will ever open it again.
Two consonants, two vowels. One word that can reduce my walls to ruins.
One word without meaning when you don't have one.
A home.
