So if you’re half of a couple, what happens when you go canoeing? Do you or your partner start blaming each other every time the canoe seems to misbehave (“Didn’t you see that rock?”)? Do you get into a huge battle that ends with one or both of you jumping overboard, swimming to shore, and not speaking for an hour? Or, when you hit a rock, do you work together trying to figure out who should do what, and get along as best you can?*
