A few years ago, I was walking through the hospital parking lot, and I tripped over one of the parking dividers and fell hard.
While I was lying on the cement, there were hospital workers walking past me and NOT ONE OF THEM stopped to ask me if I was all right. After several minutes of nursing a badly scraped knee on the ground, some construction worker came over to ask me if I was okay.
I always feel baffled by that situation. I was in a hospital parking lot, for god's sake. These were medical professions walking past me. Why didn't they help me?
