Thats a good question. I heard a couple of loud thumps on my Car some couple years ago. I look and saw some 18/19 year olds having thrown wet sponges at my car from side of road. I guess could of been bricks, but was odd seeing such older teens doing the type of thing 12 year olds might do, lol. My opinion, our young people are being absoloutely RUINED by the Internet & Social Media etc and they are Not growing up mentally ,they simply are being brainwashed in all areas by Internet. That is my take on it, now shoot me down and say im wtong internet/social mdeia is fine etc !
