Small injuries add up. Who hasn't been scarred by life in one way or another? Bruised by desire, cut by love, falling down on the job?
You know, those small, slightly discolored, sensitive spots we think have faded away, recessed to the point where we can ignore them, that somebody manages to poke in just the right way to unleash a chain reaction of hurt.
Or that sensitive person who manages to see that hidden bruise, and gently massage in some balm that helps to heal the pain you didn't even realize was still there.
Small injuries add up. Wearing them as badges can weigh you down. Setting them free can liberate you enough to go out and collect some more.
