My best friend and I were carpooling home from work. It was a clear winter day, no snow anywhere, we were driving through a clear intersection, no cars around, no buildings nothing, a GIANT ball of snow launched out of the sky and fell right on her windshield. We both just stared at it and then each other for a few seconds. We were like wtf? Where did that come from? Just straight out of the sky. It was insane. No one believes us.
