On the subject of ED asking for fruit as a way of engaging with people she met, and in light of much recent analysis here of her mental well being, I just remembered today something I read a while ago in an email newsletter, about talking to strangers being mood enhancing. Did some searching this evening and I was surprised how much there was out there. I can imagine ED would have seen some of this as well and incorporated it into her routine.

The surprising benefits of talking to strangers
I agree wholeheartedly. I‘ve coped with general anxiety since childhood, and I rarely pass up an opportunity to talk to strangers. People who know me often comment on it. I find it somehow validating and grounding, if that makes sense. Perhaps, it triggers the release of endorphins, just like hiking.
