Some of those scars on my arms are from sailing, yes, but others are from a knife. I lie about/hide them because I don’t want to draw attention to them. I’m not trying to get the spotlight (I’m rather antisocial, actually) and I’m not trying to punish myself. For some reason, it’s just fascinating to me to watch the scratches happen. Usually, they don’t draw blood, but when they do, it’s also oddly fascinating to watch it reflect the light, settle, and dry before it’s washed off.
