Me, this morning, driving carpool: "I can't believe people keep knocking down those bricks around the driveway. I have to rebuild that wall every two weeks. It's like I never make any progress."
My son, with even tone and not looking up from his book: "Yep, Dad, you are truly the modern Sisyphus. You should write about it. As much as I like to hear about this every morning, I'm sure others want to hear about it even more."
Butthead. I wish I had said it.
