it's about a friend of mine...

I'm really worried for his safety. his mom is being verbally abusive on more than one occasion and im worried that she'll keep to her threats. He's been told by myself, and a couple other friends to talk to an adult about it but he thinks he's being over dramatic. when i said that someone should do it he vehemently said no. Im worried about him but im not sure what to do ):

right now im just keeping his mind off the subject. but i think something should be done still.
