Sa at New Jersey grey day

Last night I was in the New Jerseys greyday pit on the right, my mother was next to me. While mid set when the boys were on this guy kept purposefully rubbing his private parts on my mothers behind, He also grabbed her arm and grinded. She couldn’t stop him because it was very crowded she had nowhere to go, And he was very tall. I think alcohol should not be allowed at any greyday’s because every greyday I went to the people who drank are the ones who are extremely violent and disrespectful. The past two greyday’s ive been to have been extremely bad experiences due to the intoxicated people, im not against drinking as I do occasionally drink on special occasions. I just think it should not be allowed at concerts.
