When we were in Italy, a friend of mine there was telling me that he thinks life goes in circles. I pondered this for a moment, and then decided that my life goes in rectangles. You're just going along, doing your thing, and then life takes a huge 90 degree turn. Then you go along again, and just when you're starting to get used to things, your life takes another huge turn. And then, after about four huge turns, you find you're right back where you started.
