“Imagine you were going to spend the weekend at a friend’s house on a little island off the coast of Maine. There are no shops on the island and you won’t be able to leave while you’re there. Also, you’ve never been to this house before, so you can’t assume it will have more than any house might.
What, besides clothes and toiletries, do you make a point of packing? That’s what you’re addicted to.”
