Scratching the Surface
Re the "Human Scratch-Pad" and dermographia [extreme sensitivity of the skinJan. 19]: as a long sufferer of this complaint, I thought you might be interested in knowing that it had one positive aspect for me. When I was younger, nothing quite so impressed a girl on a day at the beach as emblazoning her name on my forearm in bright, raised letters. It served to cement a number of relationships. Alas, the girls get older and wiser (and more difficult to impress), and dermographic penmanship no longer does the trick.
