Illegally passed in a no-pass zone. Then he flipped us off and intentionally went really slow in front of us. And then sped off through a school zone because he was still angry. Dude, we had a giant piece of plywood on our car! We werent confident in how secured our load was, so we were TRYING to go slow so it wouldnt fall off and hurt someone. Slow down and take a breather next time, man! Not everyone is out to get you! Jesus.
