When my grandmother was close to or around 90 or so she and my mom were at a mall and grandma started up a down escalator. She figured it out pretty quick, but I guess something inside clicked and she took to it with a “I can do this s*** challenge accepted!” anyways. She made it to the top, but my mom was flipping out because she was like she’d finished a marathon when she’d scaled it LOL...
It was incredibly funny picturing an elderly lady running UP the down escalator and making it to the top! I’m reasonably fit and younger than your grandma, but I don’t know if I could make it to the top. She’s an amazing woman! Your Mom is a great sport too. Still laughing!
