When Scotty was about 2 year I had an occasion to take him with me to a construction company in order to work out some plans on some new enclosures. As usually Scotty was the center of attention. He came into the building and went around to all the employees to see what they were doing. He soon found a hard hat and put it on. The hat came down over his eyes and he was unable to see where he was going but he would not remove the hat. After he had run into several pieces of furniture and wall, he started walking erect with his hands out in front of him feeling for and obstacles that might be in his way. The entire office staff was laughing which only encouraged Scotty.
