Dance ball of parasites

Rodents and parasites often settle in forgotten buildings and fight for survival, but due to their parasitic nature, they destroy their own habitat. It's like that everywhere, unkempt clothes, yards, factories, cities are threatened by the same thing, when healthy goals disappear in society, then parasitic thoughts take over the mind, their existence in a foreign body seems to turn into a great dance ball, which fights only for self-preservation.
