I knew her son in college. We were in a video production class together. We weren't close friends, but we got along well enough and were part of a group that would often have lunch together. I've often thought about asking her how he's doing, but I'd be afraid that she'd perceive my asking as an invasion of privacy and respond with anger.
Diana appeared in two of his productions for that class. We produced remote videos and studio productions and she appeared in one of each. It was rather fun, being in the control booth, watching her act. We weren't allowed to stop tape during the studio productions, so the experience was rather DS-like. I didn't attempt to speak to her, but she seemed very nice.
