Once there were two bulldozers. One of them allowed its owner to wash and oil it daily while the other didn’t allow the owner to do so.
One day a construction agency called the owner of the bulldozers to demolish a shop in order to create a primary school. The owner accepted the offer and took both his bulldozers to the site.
The dirty bulldozer was eager to show its power in order to impress the humans and irritate the clean bulldozer. It began thumping its metallic blade heavily on the ground and the owner sat inside it to crush the shop. But since it was too dirty and had not allowed its owner to oil itself, the nuts and bolts could no longer take the pressure and the metallic blade broke off.
The owner abandoned the dirty bulldozer and sat inside the clean bulldozer in order to demolish the shop.
After returning to his home, the owner had no choice except to dismantle the bulldozer and sell it to a scrap dealer.
