Neha went to the lakeside for a picnic with her friends. Suddenly they noticed a man drowning in the lake. Everyone was frightened but Neha asked them to stop panicking and take the man out of water. After the man was rescued, he was found unconscious. Neha then suggested that mouth-to-mouth artificial respiration should be given to save the man. One of her friends did as she guided.
