So I head to campus for my oral in FA 122( Multi-Engine Private) and after it was over I head back to my car to exchange the Piper Seminole information to the Cessna C172 stuff because I was going up to get my rental currency renewed. As I get back to my car I see white marks which I think scratches all over the driver side of my car. I was, " ****************" at someone keyed it or hit my car when backing out. Took a closer look and rubbed it off found out it was used dried gum. Someone strung it along my car. What in the hell is wrong with college kids/people?
