Embarrassing my wife, Margaret, is not -- I swear -- the goal of my life, but if embarrassing her were my purpose I could happily retire, having succeeded beyond my wildest expectations many times over.For example, on our last wedding anniversary (romantic devil that I am) I thought I should take her out for an experience in elegant dining.Her choice -- Mexican food -- was a bit of a sacrifice because while Margaret likes spicy food, it doesn't agree with me.
