There are people in this world, including kids, who have trouble expressing their anger.  They find themselves in a situation where something happens to upset them, and they wind up in a state where even the tiniest trigger sets them off.  WADR Leave is meant to help people, particularly kids, handle any anger management problems they might have by providing them with a nonverbal and non-confrontational medium to express their inaccessibility before escalating.  When the user needs space, WADR Leave’s wooden spikes rotate out from against the wearer’s forearm, where it is situated, as a way of showing this.
