If you put your mind to it, you can come up with excuses for why it makes sense to do just about anything. For instance, if it’s Sunday and you really should go shopping to stock the fridge for the week ahead, but you’re all settled in to watch TV, you can reason that the supermarket coupons probably aren’t valid until Monday. Or, if the leaves are four deep along the garden wall, you really shouldn’t rake them until the last ones fall. If the last ones have fallen already, didn’t you read someplace that letting them molder right there is good for the soil?
