My friend's mom died from cancer a few months ago. His dad came to me today and asked if I could maybe talk some sense into him. Whilst no one expected him to take it well, he has suddenly gone into a black hole, becoming angrier and angrier, to the point where he is starting to do things that are illegal like stealing and more. I do feel for him and have listened to his anger as no one else in my friendship group will. He says that we couldn't possibly understand how he feels and he is probably right, we couldn't. I do want to help to him but I don't know how I could talk some sense into him.
