"I ate the dog and choked on its tail" - proverb about the most absurd end of a great work.
๐ต What's the irony: the entire main volume - the very same "dog" - is already in the back. The most difficult stage is completed, the energy is expended, the success is almost in your pocket. But at the last moment everything is spoiled by a penny.
๐ต The essence: This is a metaphor for an offensive defeat at the finish line. When a person has finished a tremendous task, but loses concentration and "chokes" on the final detail.
๐ตMoral: The scope of the work done does not guarantee success if you relax one step before the end. The tail is small, but it can be deadly. ๐.
