The plumber was due to install the bath.
And then the phone rang.
"I've got good news and bad news," said the expected plumber. "Good for me but not so good for you."
Oh, yes. What is the problem?
"I'm in the car and on the way to the hospital with my wife - our baby is coming early! Sorry, but I won't get there for another three days."
So, not so much 'expected' but 'expectant'!
