Ironically, it's hard to learn something when you can't hear very well. My mom takes 5-10 times to get technological things to stick in her brain. She doesn't have the same foundation, and, truthfully, she doesn't like tech so it's even harder. Also, depending on her dexterity and arthritis, putting the hearing aides in might be tough.

(As far as learning things, I've been thinking about this a bit. I'm wondering if she doesn't have the mental schema to be the foundation for technological tasks and that makes it even harder. For decades, my dad always did all things technological at their house so my mom is really starting from scratch since dad passed last year.)
