Rebecca Mehra, who shared their story in , noticed the pair sitting in their car outside the store as she was going in.

"I went to the grocery store this afternoon. As I was walking in I heard a woman yell to me from her car," Mehra wrote. "I walked over and found an elderly woman and her husband. She cracked her window open a bit more, and explained to me nearly in tears that they are afraid to go in the store."

: "Afraid to get sick as they are in their 80s and hear that the novel coronavirus is affecting older people disproportionately. And that they don’t have family around to help them out.

"Through the crack in the window she handed me a $100 bill and a grocery list, and asked if I would be willing to buy her groceries. I bought the groceries and placed them in her trunk, and gave her back the change. She told me she had been sitting in the car for nearly 45 (minutes) before I had arrived, waiting to ask the right person for help."

She ended her message by asking people to remember others, especially those who are extra vulnerable, in great times of need like these.

"I know it’s a time of hysteria and nerves," she wrote. "But offer to help anyone you can. Not everyone has people to turn to."

Twitter users replied, thanking her for showing compassion.

"Thank you for being the kind soul this couple needed today!"

"This warmed my heart and also hurt my heart,"

"Kindness matters. We all get by with the help and support of our neighbors. Let’s look out for each other,"

Infectious disease expert , senior scholar at the Johns Hopkins Center for Health Security recently recently explained to Prevention.com that the majority of COVID-19-related deaths have occurred in the elderly.

"Above age 50 is when you start to see more severe complications," he said, adding that older patients have a harder time recovering.

They’re especially susceptible if they also have underlying health issues, like heart and lung diseases, , and other immune-suppressing conditions.
