I cut my arms badly during my teens, and although I've not done it for over ten years now they are still a complete mess. I've got a selection of thin, lacy long sleeved tops and shrugs that I wear when I go out in hot weather so that nobody ever sees.
However, I've got an 18 month old daughter now and it's really been on my mind recently that at some point in the future she will see my arms and ask about it. Whatever do I say?
