The History of a Mower Repair Shop

Rocks were being thrown at the mower repair shop. The staff thought it was kids in town, or someone trying to pist them off. But when they went to go look one day and they didn't see anything, they just kept hearing the rocks,. They went back to work in the garage. And i guess there's these things on lawn mowers called spanners which are basely like a fan. One of the employees sees this and with his hands, like, stop it so it'll stop spinning. And after he's stopped it, it starts spinning again. No wind. He is just doing it on his own. Why? There's already a ghost behind you or what
