what happens when you have a small house

I'm at a coffee house here in Corvallis, writing, because my house is 750 square feet and Chuck is home.  I am trying to write a chapter in which my character, Tree, foreshadows the arrival of Jimmy while she and Mavis drink coffee (hey, where did I get that idea?) beside the Salmon Street water fountain in Portland, but mostly I am spying on other customers. Not that they are that interesting, but I can't help it.
