Heart lesson #3: post-heartbreak survival. The heart is resilient, I mean literally. When a body is burned, the heart is the last organ to oxidize. While the rest of the body can catch flame like a polyester sheet on campfire, it takes hours to burn the heart to ash. My dear sister, a near-perfect organ! Solid, inflammable.
It's what everyone wants when they're breaking someone's heart: to be rid of the person and yet absolved of guilt, of the unhappiness they've caused. They want their rationalizations heard and gulped up by the wronged, and they want their victims to go away, peacefully. To never be haunted again.
