It's where your spare contact lenses are

Dear future hubster,

if you've been on the road for a certain amount of time and are longing for a real bed and not having to dig in your suitcase every single morning, then it doesn't matter that you're not citizen of the country you're going back to. When, after 5 hours of waiting in transit, finally they call your last flight for boarding, you will say, and mean it: "At last. I'm going home."
