A student comes up to the reference desk and asks if I can help him with a problem with his computer. We have two areas with computers on this floor - some are in the center of the floor, among the circulating collection, and others are in a separate lab, off to the side, next to the reference desk.
Me: "Okay, I'll come over and take a look."
The student starts walking and I follow behind him. He is walking toward the main computer area, but as we pass by the lab, he starts walking slower and slower, and finally looks at me to see where I am walking.
