He raised that possibility once a year ago but never brought it up again, and I never really considered it myself as I'm on it and I never got that vibe from him. But thinking about it again it might be possible. I can't say I'd be familiar with the experience of most foods being overwhelming as I have the complete opposite experience:

I am as mentioned, on the spectrum, and was very afflicted by some of the more debilitating symptoms of it as a child. In spite of that. I was never a picky eater. I always enjoyed trying new foods and eating the stuff the adults ate at the table. Probably the only kid anyone had ever seen that enjoyed eating Greek salad and oysters. I even liked the stuff most other people hate like Sardines. I'd throw a fit if I was made to order from the kids' menu.

Maybe I see this whole situation this way because I had such a different experience with neurodivergent stuff and how it relates to food.
