You know, in geometry, a point is not a dot. A dot is the graphic representation of point. Because a point has no dimensions. You could never see it. A point is the intersection of two lines. Or (I figured this out myself in HS) the intersection of three planes. (A line of course is the intersection of two planes.) Yeah, they say you can't see a line either, because it has length but no width. But I wondered more recently if that's true. The border between you and your neighbor's property is a line. When you look down at that your looking at a line. Aren't you?
No, you are looking at the intersection of two planes of legally defined shapes and depth (you only own the land to a certain depth unless you have mineral rights).
