I went through a period in my life when I... had some mental issues because of a lot of stress at school and I took a Sawzall to my arm and now I have some large scars on my arms. I haven't done anything like that in years and I have for the most part worked through my inner demons but the scars are literally still there. Now I don't give a shit what people think of them so I wear short sleeve the shirts and tank tops where ever I go. I've also been working out for a bit so I have some muscle mass on me. When talking to girls sometimes I notice them staring at my arms. How should I approach this so I don't sound like I'm crazy while being honest at the same time?
