After a few years of marriage, there are little things that begin to interest you: subtleties, and nuances that, after a while, make you wonder. "Why did she say that?"... "Wow, I didn't expect that answer!"... "There's that look again." And then there's always the push: "Please, not tonight, honey, I'm too tired." Put them all together, and you begin to suspect that something is wrong in your happy little home.
