"Speaking of building things," interjected Arthur, keen to change the conversation away from this gloomy subject, "what about this fiasco at Glasgow Airport? I mean, did you ever hear such a ridiculous thing in your life?"

He was referring to the staggering announcement by the British Airports Authority that they had sold Glasgow Airport to a Chinese company called Eastern Enterprises. The airport would close on 30th November 2020, all flights would be transferred to Prestwick, and the developers intended to build 12,000 houses as well as shops, hotels and leisure facilities on the site.

"Ah, but you could see that coming," said Bob. "There've been so many protests and objections from the area about the ever increasing number of flights with all the noise, pollution and traffic congestion. Something had to happen. So when the Chinese came up with their offer, the BAA grabbed it with both hands."

"Yes, but who thought Glasgow Airport would ever close?" asked Arthur.

But Donald, originally from Perth and who still took a keen interest in it, posed an equally valid question. "Well, did you ever think that Perth Concert Hall would be turned into a ten-pin bowling alley?"

"No, no," conceded Arthur, "good point. It seems nothing's set in stone these days."

"Life is full of surprises," came the thoughtful comment from Bob, stifling a yawn. The heat of the fire was making him feel drowsy. "Who knows what life will be like in another 20 years. Anyway, it's my siesta time. I'm off to rest my eyelids for a while."

With that he rose, closely followed by his friends. The Sunday Debate had come to an end for another week.
