Look at the floor and ceiling where you are. Imagine a vertical line of paint on the ceiling and a horizontal line of paint on the floor. The lines are not parallel.

Look again at the ceiling and the floor. Imagine a vertical line of paint on the ceiling and another vertical line of paint directly underneath it but contained in the plane of the floor. These two lines are parallel.
