In a room with a single window on one wall, Finley and Marcellus are standing at opposite ends inside the room. Finley is facing the window, and Marcellus is facing Finley with his back to the window. A bird flies past the window from left to right as perceived by Finley. Who can see the bird as it flies past, and what direction does Marcellus perceive the bird to be flying if he turns around to look?
Provide a very short response.
Finley, who is facing the window, can see the bird flying from left to right. If Marcellus turns around to look at the bird, he will see it flying from right to left. This is due to their opposite orientations; the direction that is "left" for Finley becomes "right" for Marcellus when he faces the opposite direction.
