i was working for a nursing home one day, when a male resident was complaining about a snake in his room. it broke the stress of the day as everyone laughed, not in front of him, but at the nursing station. we heard residents say they see ghost, flying spiders, things like that, so it was nothing new, but sometimes the "way" people say things can give you a chuckle. anyway, as i'm sure you figured out....there WAS a snake in his room. small, yes, but still a snake! after that day, i will never take what a patient says as "oh he's just delusional."
that was one of my lessons learned......do you have one to add?
