Final answer:
Four friends disregarded warnings, entered deep water during a picnic, and started drowning. Local fishermen heroically rescued them, and they were rewarded for their bravery. The moral reflects the importance of heeding advice and understanding your own limitations.
Step-by-step explanation:
Once four friends excitedly decided to go on a picnic at a nearby canal bank. Despite being reminded that none of them could swim, they chose to ignore the warnings and ventured into the water. Their playful shouts quickly turned to cries for help as they realised they had drifted into deep water. Fortunately, some local fishermen heard their desperate pleas and rushed to their aid. After a tense struggle, the fishermen managed to pull the friends back to safety. Grateful for their rescue, the friends rewarded the fishermen, promising never to underestimate the power of nature again.
The moral of the story: Always heed warnings and know your limits. The fishermen's bravery reminds us that heroes often appear when we least expect them, but it is better to avoid putting oneself in danger in the first place.
