I think this whole song is a fantasy; the narrator is looking around his lonely apartment "where I spend all my days, all alone" and imagining what what it would be like to show it off to another person.

Why not imagine an entire date, then? And really embroider the fantasy, add dinner after a lunch date to keep it going.

And then, as long as you're imagining things that would never ever happen--like having another person over--why not go all the way and imagine that person would marry you, too?

I think this whole album is about being incredibly lonely, and this song is the thesis statement.
