It’s a funny thing when you look at this. An actual person who literally slices themselves open on a daily basis just to get away from the emotional pain and come back to a physical state. I bet there’s someone you’ve said something rude to that went home and add a another scar to their already beautifully scarred skin. So yes in a literal sense you just made a mark in their life and you are now embedded into their skin forever. When I put it that way makes you think a little huh. It doesn’t take much to be friendly; no matter how much you can’t stand a person. Be kind. Because even though what you think is harmless could be the death of them.
