I know is tempting. Really, really tempting to pick it off. But it leaves a horrible scar. I fell about a month ago down on a ditch while hiking and I shredded my left arm. I had scabs everywhere. I started to pick them off (which is nasty to a lot of people), but it was so tempting. Now I have a scar that won't go away. It makes me embarrass to wear a t-shirt.
