I think this has happened to everyone - you get these small scars or random bruises on your body and you have no idea how you got them.
I guess I never really wonder the how or the when of it, instead I always wonder what was I doing when I got them. What was occupying my mind so much that I didn't register the pain? Which train of thoughts could overpower the pain signal to my brain? What was I thinking?
And more importantly, was I thinking of you?
