When our children were much younger, Eric and I used to depend on rock-paper-scissors to make many decisions for us. Who should change the baby's dirty diaper? Who should get up to comfort the crying child in the night? Who should feed the baby in the high chair? Who should respond to the call from the bathroom for "help"? For these decisions we often immediately put out our fists for the challenge. Now, I think that this led to an equitable sharing of these duties, but Eric thinks I won more often than he did. (Winning, of course, means NOT having to do the unpleasant chore....)Obviously this method won't work for any weighty decisions, but for mundane things it's great. Now I realize there are people who take rock-paper-scissors VERY seriously. But for us it remains a lighthearted way to make a quick decision about things that don't really matter in the long run.
