My husband has a service buddy who lives in Minnesota. He's one of those rough, tough guys who's been shot twice, been in a few bad car wrecks, plane crashes, etc. One day he fell off a ladder and cracked his skull open. He was rushed to the hospital where he remained unconscious.
The doctor and nurses didn't expect him to recover, telling his son that he'd probably be a vegetable. "You don't know my Dad," the son said. "He'll come through this."
