I have tried talking to schizophrenic, delusional or mentally ill people who hang around at a university and are sometimes homeless and it is more boring than talking to people who are not mentally ill because the conversations are less repetetive
Except two actual University students who told me they had schizophrenia and took classee you need calculus to get into seemed rrasonable to talk to and I would not know they had schizophrenia if they did not tell me
