GURGAON: Rawel Singh , who is 82, went out for a morning walk on the morning of December 21. But he could not remember his way home.Two days later, Mohit Agarwal was riding his bike home when he spotted a frail, old man, clad in boxer shorts and a sweater, standing outside Good Earth City Center , a mall in Gurgaon. He was pale and shivering, and looked lost. Visitors drifted in and out of the mall, cars raced past and people walked by.It was 7 on a weekday evening and everyone was keen to get home. But Rawel Singh had no clue where he had to go, where he was, or what to ask. He just stood there.Most would have seen Singh as they passed by. Only Agarwal noticed. That’s probably what made him pull up near him and ask if he needed any help. It started a chain of events that got a man with a weak memory reunited with his family through the resolve of a group of strangers, scripting, in the process, a touching tale of humanity and compassion that is rare metal these days.When Agarwal first tried to speak to the man he had spotted outside Good Earth, he could not elicit anything from him. The man barely spoke. When he did, he was incoherent. Agarwal rode home and came back with his friend and flatmate Manish Sinha carrying with them warm clothes and food.They tried speaking to him again. “We fed him a little, put some clothes on him and asked him about his family. But he only mumbled in phrases that we did not understand,” said Sinha.The two then decided to take police’s help. “The cops told us the environment of a police station might scare him even more,” said Agarwal. So, they went looking for a night shelter to put him up as they decided their next course of action.But when they saw the rundown shelters, Agarwal and Sinha didn’t have the heart to leave him there. They decided to take him to their house. “We could not have left him like that,” said Sinha.Together with another flatmate, Rahool Sureka, they tried to speak to the man again. Rawel then mentioned the whole address to them --house number 110/114, RK Nagar. He had a shop in Kanpur called Bhagwant Saree Centre in Sismau Bazar, Gumti No. 5.Instantly, they put up a Facebook post, seeking help, with the name and address. “From there, one friend contacted another and so on. The word spread,” said Agarwal.Agarwal’s friend Bharati shared the post which was then seen by Saurabh Gupta, who is based in Kanpur and works for a beverages major. Gupta, along with Mohit’s friend Akanksha Bajaj, visited the shop in RK Nagar. There, they learnt that the man they had brought home was Rawel Singh. Gupta and Akanksha had managed to reach his younger brother.Singh, they learnt, had a cancer surgery seven years ago and since then his memory has been weak. When he got lost, the only thing he could remember was the name of the place where he lived decades ago with his brother.In the meantime, on December 22, Singh’s son Daljeet went to the police to report that his father was missing after looking for him an entire day. “Father generally goes out for a walk every morning in the neighbourhood and comes back in an hour. But that day he didn’t turn up for hours,” Daljeet said on Saturday after he was reunited with Singh.The family lives in a bungalow in Sector 4. Good Earth is in Sector 50, across the expressway, nearly 11 km from there. Daljeet is puzzled about how his father got there.“It’s a miracle indeed (how his father was found). I mean we keep rebuking youngsters over their obsession with Facebook. But look how social media can work,” Daljeet said, adding he had no words to thank the youths who brought back his father home. “Nobody takes some stranger home like this in today’s world,” he said.
