There is no one at home, all the animals are shaking, I sit with the child in the room, read a book and suddenly I realize that someone is talking quietly. Words can’t be heard, but clearly. At first I thought the roof was running, I went out of the room, no voices. So I don’t think the head :) I started looking, in a couple of minutes I found the direction from where the sound comes - a desk. Almost an empty table, on which, except for a few sheets of paper, there is nothing persistently telling me something. There were suspicions about my mental health. I looked every centimeter of the table and found it. From the wall, behind the table, the wires of the radio points, once dismantled and isolated, were torn. Whether the children were wrapping something there, or the cats were wearing, in general, the isolant fell down, and the wires touched each other. And not tightly closed, namely, touched. Accordingly, there was a small KZ that made the wires vibrate. But this really was not all, the carelessly dropped A4 sheet of paper from the top on the wires became a membrane and completed the construction. And that's all the broadcast :) Loud, but clear enough to think that the roof is going.
