Bobby came in with a girl I hadn’t seen before, and usually I feel a little funny if a stranger sees me working that way, with those leads clipped to the hard carbon studs that stick out of my stump. She came right over and looked at the magnified image on the screen, then saw the waldo moving under its vacuum-sealed dust cover. She didn’t say anything, just watched. Right away I had a good feeling about her; it’s like that sometimes.
