I think something that is missing in the minds of the “but you could just…” posters here is that the mindset of the OP doesn’t always come from laziness, immaturity, or the inability to understand how to pack a sandwich, it sometimes comes from crippling or barely functional depression.
I work from home and the thought of even making a sandwich most days in the middle of the day is just too much. I don’t want to make a sandwich; I want to go back to bed for eight to ten years and I agree that lunch is the fucking worst.
(But so is breakfast, and dinner, and all of the meetings, and work, and life generally speaking, etc.)
