Defrost

So on my way home from my friend's house the other night, I turned on the car and realized every single window in the car was foggy. I thought nothing of it, turned on the defrost and drove off. It wasn't until I was actually on main roads that I realized the defrost wasn't helping at all. But after I hit a few more buttons on the dashboard, it kept getting worse. The front windshield kept getting foggier and foggier as I drove along. It was pretty embarrassing because I slowed down a lot since I could hardly see. I finally pulled into a gas station and sat there for a while, figured out how to get the fog to go away, and drove off.
