"What’s worse? New wounds which are so horribly painful or old
wounds that should have healed years ago and never did. Maybe our
old wounds teach us something. They remind us where we’ve been and
what we’ve overcome. They teach us lessons about what to avoid in
the future. That’s what we like to think. But that’s not the way it
is, is it? Some things we just have to learn over and over and over
again." -Greys Anatomy
