“You see a figure ahead of you, solid, three-dimensional, brightly colored. Moving and obeying all the laws of optics. Its clothing and posture is vaguely familiar. You hurry toward the figure for a closer view. It turns its head and—you are looking at yourself. Or rather a perfect mirror image of yourself only—there is no mirror. So, you know it is your double.

If a teacher creates a disturbing environment at the school, then that teacher has to go, even in the middle of the term.
