Practice taking idioms literally. When told to calm down, for instance, slowly lower yourself to the ground while repeating calm, calm, calm, calm, calm. If someone says chill out, proceed to the refrigerator and open the door, visibly basking in the now-distributed chill. When asked to hold your horses, find your toy horses and hold them out in plain view. The world must know—must learn—that its language doesn’t make the sense it thinks it makes, but a different kind of sense.
