At my house, we’re deep into a host of summer projects and are having our usual communication difficulties. Yesterday my brother Charles and I were trying to help my husband Michael tie sheets of plywood to a cart so they could be transported to a work site. “Put the rope under the board. No, not all the way under. Put it under and over the top.” My mentally challenged brother is confused and frustrated as he tries to put the rope where Michael wants it. “No, loop it over.” I’m eager to help but I haven’t a clue where the rope is supposed to go.
