Sometimes it is exactly what they're doing. 15 years ago, shortly after surgery to remove a tumor from my femur, I ran into a physical therapy assistant whom I'd been working with when my doctors thought my leg pain was a soft tissue problem. He said he'd heard about my surgery and was glad I was doing well, and then as we parted ways he cheerfully commented offhand that when I'd been working with him and his supervisor, "I thought you were making it all up!" (I still feel angry about that occasionally, all these years later.)
