Margot apparently wants to return to our pre-Jane status as a family of four. The reason, however, is not one that you'd likely guess. (Hint: we think the chair is meant to be used in a lion-tamer way).
Margot: "Dad, I wish we didn't have Jane."
Don: "Why is that, Margot?"
Margot: "Well, if there were wolves in the walls, and they came through, we could each hold a leg of a chair."
