“Nothing is easier than taking off the gear ­case.” Comment on or continue this sentence in the light of what actually happens.

The author’s friend wanted to check the chain of the bicycle. For this, he began taking off the gear­case. The author tried to dissuade him from doing that by telling him that if anything does go wrong with the gear­case of a bicycle, then it is cheaper to sell the bicycle than set about repairing the damaged gear­case. However, his friend disagreed and said that nothing was easier than taking off a gear­case. The author notes with sarcasm that his friend was indeed right. In less than five minutes, he had the gear­case in two pieces, lying on the path.
