Your opinion. His chief should be defending him instead of capitulating to the current hysteria.

One particular schizophrenic (she is dead now
) had a wide variety of delusions. Most of them common - people moving things around in her house, stealing her blood, people on the television talking to her. Her top delusion on rotation was related to a "Negro Postmaster in Louisiana" and a tribe of "Pygmy Negroes". In her particular case, you could almost stop all agitation by asking questions, but not in a serious way.
I would ask things like:
"I'm sorry to hear that, are the pygmies able to get into the house because they are so tiny? How do you think they find jeans in their size?
