It is an undeniable fact of life that you can't put two people in the same room without one of them eventually getting in the way of the other. In marriage, multiply this by ten.
Too many marriage books see this as a problem. I believe it has a divine purpose.
Being annoyed by your spouse can actually be a healthy thing to work through, provided you do it in the right way.
In C.S. Lewis' classic book The Screwtape Letters, Screwtape, the mentor demon, writes to his protégé Wormwood:
When two humans have lived together for many years, it usually happens that each has tones of voice and expressions of face which are almost unendurably irritating to the other.
Our enemy's goal is to take a natural occurrence and use it to create marital dysfunction.
At the moment, I can't honestly pinpoint a single tone or facial expression of Lisa's that is "unendurably irritating" to me, though I do remember a time when I asked her to stop hitting the passenger side car window with her fingernails as she pointed something out. Lisa's an extrovert, which means she hasn't seen something fully until everyone in the car has seen it too, even the driver who, ostensibly, should be keeping his eyes on the road. I'd hear that familiar, "click, click, click," and then Lisa saying, "Honey, you have to see this!"
Why should fingernails clicking on the window bug me?
