She kept this up through her eighties when she passed.
Your Grandma sounds like she was a lot of fun, like mine was. My Grandma was funny without even knowing she was funny, that's what made her so funny.
She spent her last three or four years living in a retirement home. She had dementia so we didn't have much choice. It was a cool old house in a small town in Upstate New York. It was a homey nice place, but it wasn't where she wanted to be. One time when I was visiting her, she was having a good day, mental clarity wise. I'm sitting on the porch with my 89 year old Grandma and she says, I hate this place. I asked, why? Because Jenny all the other people here are so old, what am I going to talk about with them?, lol. I had to hold in my laughter.
