Back in 1996, my father developed an aneurysm in his brain. Didn't rupture, but the risk was there in a huge way. He decided to do surgery. Long story short, he had a stroke during the surgery, and never woke up again. Surgeon not only apologized in b person, but wrote my mother a handwritten letter and sent flowers to the funeral. Wasn't the docs fault. The stroke was in a different part of dad's brain than where we the surgery was taking place. Appreciated the doc's actions, which really helped my mother through it.
