“There are four types of people: Donkeys, Wheelbarrows, Cars and the Aeroplanes.” Karlson informed Tim. “The donkeys work hard, are very useful but wander aimlessly if unaided. Wheelbarrows are equally important, cannot wander off, but won’t move without a pusher.”
“What about the others?” Tim chuckled.
“Cars are better than donkeys and wheelbarrows, but require fuel and drivers to perform. The Aeroplanes are efficient although costly. Training and maintaining their pilots is very expensive.”
“So, where are we?” Tim asked.
“I am the aeroplane!”
“Well… What was the first type again?”
