“She talks to everyone at the supermarket,” said Cacciotti in a 2000 interview with People. "[She] listens to their problems and tries to solve them."

Mary Tyler Moore supported the statement, adding that “it doesn’t matter if a guy is yelling out of his truck, ‘Hey, Rhoda!’ She’ll ask him his name, does he have a wife, does he have any children?”

Over the past few years, Harper had been struggling with many health issues, including lung cancer, brain cancer and leptomeningeal carcinomatosis.In 2014, she told People that while she didn't want to die, she was ready.

“I’m ready. I’m ready to go,” she said. “Maybe that’s the secret. That I’m absolutely — I don’t want to, my God, I want to live to be 102. … But I am not banking on anything, really, because we shouldn’t. We don’t know what’s around the corner. I think you just take each day and get the best out of it and do what you can and have fun.”

Harper will be missed by many. May she rest in peace.
