When I was 18, I was working for a landscaping company during the summer. I cut the side of my knee pretty badly while using a hedge trimmer. When I looked closely, I could see the fat underlying the dermis...
Anyway, being a silly 18 year old, I *walked* over to my nearest coworker and told him I'd cut myself and could he call the boss and let her know? This guy, who bragged about his elite Army service, and how tough he was, turned slightly green at the sight of my leg. He went off to find my other coworker, who really couldn't stand the sight of blood. So I then had two people freaking out over my cut, while I was just like "Umm, can someone get a hold of Boss so she can take me to urgent care?".
Boss showed up, and took me to Urgent Care. The doctor I saw actually gave me a choice of stitches or butterfly strips. He said it was because my knee moved so much that any stitches he put in would have to be loose enough to allow for the movement, and would do about as much to narrow the scar as the butterfly strips. I ended up not getting stitches. My scar is about half an inch wide at it's widest point, and turns interesting colors if I'm really hot or really cold. Thankfully it's faded at last, so it's not as noticeable.
