There was a little boy who absolutely loved tractors, so for his 3rd birthday, his father bought him a little toy one. The boy thought this was the best toy he had ever gotten, and ignored all his other gifts to focus on the tractor, pushing it around the lounge whenever he got the chance, making tractor noises etc.
As the boy grows a little bit older, he comes to his 10th birthday, when his dad says "Alright son, you're a little older now, so here you go" before giving him a push-along ride-on tractor for their backyard. The boy thinks this is even better than his now quite old toy tractor, and is taking days off school and everything just to ride around the house and neighbourhood on his push-along tractor.
He gets a little older again, and lo and behold, it's now his 18th birthday. His dad comes up to him during the party and says "Ok son, you're a man now, so here you go" before unveiling a fully functional tractor for his son. "Wow, thanks Dad, this is amazing!" says the son, before taking it for a quick test drive. The tractor becomes his main transport, as he goes to the grocery store and just generally cruises in his brand new tractor.
He decides to take the tractor on it's first proper outing, and goes into the middle of nowhere, with no cell service or house to be seen for miles, and the tractor of course breaks down. It takes him a while to get in touch with AAA and his Dad to come and help him out, so he decides after that experience that maybe it would be a better idea to invest in a car than a tractor after all.
Lo and behold, a few years later, the now adult son is driving down the same road in his new car, although there's now a house there that is engulfed in flames! A lady comes out, screaming "Help! Help! Call 911, my baby is trapped inside!" The man simply stops and says "It's ok, mam, I've got this." He takes in a massive gulp of air, and the entire fire just disappears! The lady says "Wow, that's amazing! How did you do that?!" before the man responds with "Well, you see mam, I'm an ex tractor fan."
