Dan it is funny (strange) not haha that the Dr asked about suicide, we had a similar experience.
My husband Dan being a joker wore a "Cancer Sucks"
Baseball Cap to one of his treatments......they sent him to the therapist/social worker, asking him about depression etc etc. Keep in mind he had gone every day for weeks, but the day he wears this cap he is talking the the shrink and they want to prescribe anti depression meds.

Some of these doctors are nuts!
