Yes, every single day.
If I ask him to get his own lunch though, he will take it off to his room. Except sometimes he hangs around the kitchen, and then I begin to worry he wants something.
So today he hung around and I said; "You look like death! Have some vitamins."
He said people don't need vitamins if they eat properly.
I said "Exactly!!!" and nearly tried to force feed him some Marmite.
I'm not used to him actually responding to us during a meal, but he wouldn't not eat an evening meal with us.
