A few of my friends went out of town in the winter. Upon arrival late in the evening, they found that there was no wood, and the frost was noble. We decided on our neighbors "employment". We took a couple of bits, and here is the problem - traces on the fresh snow remained, hot and unhealthy. But since people were already themselves almost in wood, the elegant solution was quickly found. They foolishly took a couple of grasslands and found traces in the snow from the neighboring woodhouse to their house. It seemed as if the trees left themselves and voluntarily.
