A Beach Picnic
Jasmine, Ali and two other friends decided to go on a picnic to a beach. They packed their bags and were quite excited. They reached the picnic spot and came across a small child who was crying. They went towards that child and asked him what he wanted. He was so young that he could barely explain anything. As we turned around to look for his parents the child suddenly disappeared. We asked people around if they had seen a child or his parents or someone else with him. No one had a clue. They were shocked to see the child disappear.
They looked around for some time but found no trace of the child. They were worried and surprised at the same time. The water was gleaming like sapphire and gentle waves touched their feet as they ran on the soft yellow sand. They spread a sheet on the sand and took out snacks and drinks. They then enjoyed playing Frisbee when Jasmine tried to catch it she came across a bottle within which she found a letter. She brought this to the notice of Ali and her other two friends. They opened the bottle and saw that the paper said ‘HELP’. They looked around but nobody in trouble could be spotted. Everyone was quite happy and enjoying their beach picnic. They immediately decided to inform the coast guard. The coast guard did not react and said that it could be a prank since nobody was in trouble. So next, they informed the nearest police about whatever had happened.
The police came to the beach and first questioned the coast guard for being inattentive. Then they investigated the matter and concluded that it could be a case of kidnapping. They took the matter in their hands and investigated. We left the beach and returned to our home. A few days later we were informed by the police that the child was found with another family who took him away since he was alone and his parents were also found in a place near the beach where they were locked after being looted.

The Phone Call
On October 4, we all were decorating our house to celebrate the most long-awaited festival, Diwali. My heart was filled with excitement to meet my father after a long gap of six years. But a call from the army headquarters left us stunned. It was my father over the phone who said that he would not be returning to us this Diwali because of some emergency on the borders. He sounded much tensed and hurriedly left the phone connected. I continued to ask him what was wrong and kept pleading him to try to come back to us soon but we got no reply from the other side. All I could hear was firing, bombing and people shouting. My heart started beating faster and I couldn’t decide what I would say to mom and my younger sister, Yamini.
I rushed to my mother and as tears rolled down my eyes I tried to explain to her all that happened over the phone. Yamini was at the neighbour’s place playing with other children and we decided not to tell her anything. I switched on the TV and turned to a news channel to find that there was a mob attack at the Army Headquarters and all the reporters said was they could hear constant firing and bombing with no clue of what was happening inside. I could see the expression on my mother’s face intensifying. She couldn’t hold back her tears anymore. I decided that I couldn’t be weak and cry at this moment because I was the only one who had to console mother and give her strength. I told her that father is a hero and he will come back safe.In this tough situation sitting back at home, all we could do was pray to God. We did the Diwali puja and prayed to God to keep my father and all other members of their team safe. I remembered my grandmother telling me stories of war, of lives sacrificed and families torn apart because of war, of children unable to feel the warmth of the love of a father who had to be on duty, to fight for freedom and the nation’s independence. All those stories and the emotions evoked and came back to me today. Little do people realise the sacrifice of soldiers who give their entire life to their nation. Today we feel safe in our homes only because of the constant dedication of these heroes.
We somehow spent a few hours praying to god. Finally, the news channel confirmed the news that no loss of life was reported and all the attackers were killed. We took a sigh of relief. Sometime later we got a call from dad and he said that he was fine and admitted to the hospital due to some injuries. He also said that as soon as he would be discharged he would take the next flight to reach us. Yamini also returned back home uninformed of the entire happenings. We lit diyas all around the house and celebrated Diwali.
