The inhabitants of our planet were trying to establish contact with other civilizations for a long time. Finally, their efforts were crowned with success. The expedition of scientists has discovered a UFO base in the foothills of the Andes on the border with the Amazon forest. After the first emotions erupted, scientists decided to negotiate and discuss relations with the aliens. Earthlings have been disappointed with the results. Attempts to obtain advanced technologies failed. Arrogant refusal was like a cold shower. The aliens stated that they were not satisfied with the level of generosity and good sense in our world. When pessimism began to take the upper hand, one man offered to radically change the tactics of negotiations.
