Boredom is, as most women know, the number one cause of eating. Thus, when you’re trapped in a box all day like some sort of sexless rabbit that’s been provided with fried food options instead of vegetables, it’s easy to put on some pounds.
At first, you try to bring your lunch–you know, to save money–but then the dissatisfaction of not going outside gets to you and you end up leaving to regain some sanity. While you’re in the world that exists beyond the cube walls, you end up buying food again, because, why not? This is how you end up having three meals a day all at lunch in order to help pass the time.
