who do you think you are, running around leaving scars?

I heard a song on the radio the other day. "Who do you think you are, running around leaving scars?" We have all experienced the explosion of an emotional bomb and perhaps we have been the emotional bomb. Someone you may or may not know melts down, explodes. Shrapnel goes everywhere, leaving people bleeding in the wake.
"Who do you think you are, running around leaving scars?" I think we are human. We are all broken and hurt. And sometimes we explode, melt down and hurt others unintentionally. And sometimes we use the explosion intentionally. We leave people confused and uncomfortable at the very least and we leave others emotionally scarred.
Today, an emotional bomb went off next to me. And so while I want to ask who does this person think they are, I remember I have also been the one exploding. And the one who exploded, well, they are obviously in a lot of pain. They needed a place to explode, to let out that pain.
