"As Geoff and Anne did before us, and the others will do afterwards, we are going to move each of these items to a specific position, as in (x, y) coordinates, in the parking lots. The x axis runs this way," Uncle Red says, facing the Waterhouse House and holding his arms out in a cruciform attitude, "and the y axis this way." He toddles around ninety degrees so that one of his hands is now pointing at the Shaftoes’ Impala. "Perceived financial value is measured by x . The farther in that direction it is, the more valuable you think it is. You might even assign something a negative x value if you think it has negative value—e.g., that overstuffed chair over there—which might cost more to re-upholster than it is actually worth. Likewise, the y axis measures perceived emotional value. Now, we have established that the console has extreme emotional value to you and so I think that we can just go right ahead and move it down the line over to where the Impala is located."
