So My family ( and friend who is doing the harassing ) live in Florida. I'm in Manhattan, NYC for college at this time. My friend has always been a little " out there " Around 9 PM at night tonight nobody was home he waited for my sister which she was by her self to come home and started talking gibberish about free masons and lucifer ( and all other types of crazy bullshit). Tried to get in my sisters car untill she drove away. and messaged me on facebook saying he wanted to fuck her. I deleted those messages and blocked him but I should have saved them for proof. This is all really weird my dad is on his way home and is going to call the cops. I feel bad since he's been a good buddy for so many years but he is losing his mind. Could be drugs. Not sure why I'm posting this here but I kinda need to vent some where and I'm so far away. What would you do in this situation?
