There is something that is often said of older single men, and it is not meant kindly: They are "set in their ways." Usually I make fun of this by pointing out that younger single men are taunted with the admonition that they need to "settle down." The two jabs at single men amuse me because, as with so many other instances of singlism, they get you coming and going. If your life has a lot of spontaneity, then you need to settle down; if you have a stable routine, then you are "set in your ways." Today, though, I have a different take on the "set in your ways" rebuke: What's wrong with having a routine and liking it?
