The Repair Shop Left Behind by My Grandfather and the Clock That Runs Backwards

After my grandfather left, he left me a repair shop on an old street and a clock that couldn't be repaired - it ran in reverse. Winding, setting the time, opening the case, every gear is correct, but it just goes in the opposite direction. Grandpa has been repairing things for fifty years, and he has repaired everything well, but he has been doing the wrong thing for half his life, and he has not repaired it. On the third day after I came back, the demolition notice arrived: within three months, the shop would be taken back and converted into a parking lot. And more and more people come to fix things. The old woman who is afraid to repair her sewing machine, the bankrupt man who wants to send back a fake watch, the veteran who just wants to listen to a radio station that has been stopped... What they are repairing is nothing... Until I opened my grandfather's notes - every thing that came into this shop had a number, hundreds of them, except the clock, which had no number.
