This made me smile. There's much truth in what you say. Broken hearts are a thing and they linger. You think they are gone but they hide in drawers or cubby holes or in the lyrics of a song you shared. Suddenly, they pop up with a 'remember this? This is the cup she used as an ashtray because you refused to invest in her smoking habit.' You think about tossing the cup, but convince yourself that's silly. So, it waits to remind you again.
