In the US, I used to tutor in a college's "Learning Center", where students could come in for free tutoring from staff who'd be hanging out there. One student who came in was very elderly; I don't know her age, but I think she mentioned great-grand children. And what she wanted tutoring on was her math homework. She was studying how to add single-digit numbers. We must've worked on it for like 3 hours. I had no idea that the college taught a course like that; in fact, I strongly suspect that there was something else going on. And I was kinda confused about why she'd even want to learn about how to do basic math like that. But she seemed to find joy in it. She was certainly an enthusiastic student! I don't know if she really walked away with a strong command of the material, but it was good to see someone so happy to have gotten to study.
