I was driving down the road once in March. I noticed what looked like a drop of water moving slowly across the bottom of my windshield. I turned the wipes on and when they passed over the line, they did not break it. I watched this line move across the bottom of my windshield from left to right and when it reached the right hand side it moved up the windshield and finally stopped. I then realized I was watching my windshield crack. For the rest of the ride I was a nervous wreck, expecting the windshield to shatter and fall into my lap. Weirdest thing I ever saw.
