Идеей произведения Александра Сергеевича Пушкина «Сказка о рыбаке и рыбке» является то, что человеческая жадность и неудовлетворенность не знает границ.
In Pushkin's poem, an old man and woman have been living poorly for many years. They have a small hut, and every day the man goes out to fish. One day, he throws in his net and pulls out seaweed two times in succession, but on the third time he pulls out a golden fish. The fish pleads for its life, promising any wish in return. However, the old man is scared by the fact that a fish can speak; he says he does not want anything, and lets the fish go. When he returns and tells his wife about the golden fish, she gets angry and tells her husband to go ask the fish for a new trough, as theirs is broken.
