Crack On My Windshield

On my way to a girlfriend's house I was driving smoothly behind a damp truck on the highway, when all of a sudden I saw a tiny thing fell off the truck and came flying to my windshield. I thought it would get through and hit me on the face so I automatically ducked to cover. It's good thing I didn't swerve hard enough to hit anybody on the road. But unfortunately I got a half inch crack on my windshield. I didn't worry too much because my car insurance covers replacement of windshield anyway. I just need to make an appointment with the glass installer before the crack gets bigger.
