Pistol Pete was due at the hospital. After putting up with a problematic knee for months, if not years, he was scheduled to have keyhole surgery to sort it out. Urban-cub duly dropped him at the hospital and then came on to spend the day with us.
An hour later, the phone rang. It was Pistol Pete. There had been a major trauma and his operation had been cancelled. He would have to wait.
The very nature of plans is that they change.
