I bought a pair of silent earplugs, and the seller promised they would be absolutely silent. In order to solve the problem from the root, I decided to use it every day. After I put on my earplugs, it was quiet upstairs. Three days later, the police came to the door. He said that the upstairs had been empty for three days. However, that was the night I handed my silent earbuds to the police. There was another sound of chairs being dragged upstairs.
