We didn't spend much time with her while we were there, but on the last night she wanted to join us with some of her friends for dinner. Since I was going to be having dinner with a group of old retired ladies, I figured we could just make some polite small talk with them and be on our way after the meal.
After we ordered drinks, one of them turns to me and says "now what do you do for work?" I said "oh I work with computers", a simple generic phrase I use when talking with older people. She says "oh that's interesting, what specifically?" When I told her I was a software engineer, her face lights up and she points around the room and says "oh that's wonderful - we all did that as well, we worked at a company called Bell Labs. Have you heard of it?"
I just about fell out of my chair. For the rest of the night I was asking them all sorts of questions about their work. They were around back when you'd program using punch cards and all that stuff. It was a very cool experience - one of my favorite memories.
