I had a glass onion in my chest, You don't need to peel apart; Look and you could see my fear, Each tier a by-gone lover, Through transparent scars.
Today I've a transplanted heart, One fashioned from polyethylene; Kick it, slap it til it drips red, Bruised and bullied, wrinkled and bled. It won't crack, It can't break, I've got it framed To keep it safe
"glass onion" is the title of a John Lennon song, but an entirely different theme. He's not referring to the transparent heart, convoluted as it is. It's a great image, and his. Now ours.
