I’m in the same situation - we have a lot of dishes in our house and my partner can manage with multiple dishes… so I have my chosen dishes and then we have a pool of dishes for them to use - they’ve actually struggled with this same issue (they’re not diagnosed but might be ADHD) so while they use a rotation of plates and bowls they have adopted “the chosen coffee mug” to keep from getting overwhelmed by piles of mugs on random surfaces in their office.
