I've got quite a few scars.
One is on my left knee where a white fluffy kitten named snowball thought it would be cute to use my knee as a scratching post with one of her claws.
Another big one was from when i was almost 15. I went to cross the street and some old lady going 45mph in a 25mph zone hit me. I flew a good 5 feet into the air and the sidewalk decided that it was going to take a nice chunk out of my arm.
I used to work in a sub shop and i managed to somehow miss this massive glove that i was wearing to take out the bread from the oven. That wasn't a pleasant one.
If you look really closely at my body you'll see the scars from when i used to cut. Scissors were my weapon of choice because the pain was just as good but didnt require too much medical attention. I still think about it as well, but i dont miss those days. If i want the high i used to get i just spend alot of money on a new tattoo.
I'm the reason why they put CAUTION: SHARP BLADE on things like saran wrap and aluminum foil.
I always put cling wrap on my new tats while im sleeping so it stays moist and the scabs dont fall off. I was getting ready for bed and was about to cover the one on the back of my head. I pulled off a chunk of cling wrap and my knuckle got caught in the blade. Its on my right middle finger starting at the base of the knuckle going past it. I was far too stubborn to go to the hospital (which i really regret now) and put it in a splint for 2 weeks. After i thought it was healed, i managed to split it open at work in front of a very cute lesbian couple and my boss. (She still makes fun of me for it). So i put it in a splint again for 2 weeks. Now its been nearly 3 months. I still dont have full movement in it, it still hurts very badly everytime i touch it, and my finger has this large mass of scar tissue on it. My mom, and people in the health and medical field are convinced i may of cut a nerve or two and possibly my tendon.
What did i learn? Its very possible to do what you thought was only a myth. I used to think you'd have to be pretty stupid to cut yourself on something like that, until i did it.
I think that with scars, you cant put them in either category. You have to go through some pain to get them, which would be considered a battle scar. On the other hand, each scar tells a story and in someway you had to grow as a result of it.
