A person jumps in the middle of a room over a green floor, while others look out a window.
The people are watching out the window for their friend to return while one them has just seen a spider and is trying to squish it.
Others can look out a window for many reasons, not only for their friend to return.  Jumping over a green floor does not infer that a person has just seen a spider and is trying to squish it.
