"We meet people and fall in love. And when we part, they leave marks for
us to remember them by. Our lovers sculpt us. They define us. For
better or worse. Like a pinball, we slam into them and rebound in a
different direction. Propelled by the contact. And after their parting,
we might be scarred. But stronger. Or more fragile or needy or angry or
guilty. But never unchanged. Our lovers linger inside us like ghosts.
Haunting the corridors and deserted rooms. Sometimes whispering.
Sometimes screaming. Invisible but… always there. Waiting."
- from the UK TV series 'Being human'
