Past is past, whatever the hell that means.
It is never easy to just cast away the dreadfulness of this past. One can fool himself that he’s finally over and done with it. He puts up a wall around him and spend his days creating a heart of stone inside hit chest. He walks around town, gives smiles to everybody and takes the same from them. Life’s shitty good.
One day, he notices a crack in his wall. Foolishly thinking that a small break wont do much harm. The next day, the wall’s gone. He becomes so exposed and vulnerable.
