A meal for one can still be plated nicely. Making things beautiful is a way to respect yourself.

Care taken when nobody is watching is the kind that says something about you rather than about your audience. Eating standing up over the sink is efficient and tells you that you were not worth a plate. Taking two extra minutes is not vanity, it is a small statement that your own ordinary evening counts. Nobody else needs to see it for it to work.

Make one meal properly for yourself this week, even a plain one. Put it on a real plate, sit down, no screen. Then notice whether the food tasted different, because people usually find that it did.
