I tried this - I pointed out to my moaning and complaining wife that she had as many pairs of shoes as I had cameras.
BIG MISTAKE. I am embarrassed that, as a married man of many years, I was so foolish.
My wife was in the car and heard it, but I didn't say it to her. I made the shoes comparison when a friend of hers asked me why I needed so many cars. It's just exchanging one rhetorical question for another.
