Many years ago, my wife and I were students, had a small family, and had little disposable income. We had one car that had a cracked windshield. The crack wasn’t substantial, but being somewhat of a perfectionist, it bothered me. The only long-term solution was to replace the windshield, which was not in the budget. I lived with the cracked windshield for a couple of years until finally we had saved enough money to replace it. The new windshield was perfect, and I was almost deliriously happy to be rid of that unsightly crack. About a week later I was driving on the freeway. As I passed a large truck, it kicked up a rock that landed squarely on my windshield. It left a large crack.
