One problem for any family member who lives with someone like this is , if that person is legally an adult, you cannot make them show you their blogging rants, enemy lists or lists of favorite contacts if they don’t want to. It is possible his mother did not know just how sick he had become. He knew not to mess up his free rent situation.
