Which is why description does not come naturally to me, and I suck at it.
That being said, it has (belatedly) occurred to me that one way to contrast Alex and Ostheim in this book is through their decor. I see Alex as liking open spaces, high ceilings, huge windows, and bright colors--whereas Ostheim goes more for dark woods like mahogany and walnut, lots of paneling, and close, crowded rooms. Alex's house is a castle; Ostheim's house is a den.
Someday, maybe I'll be actually good at this writing thing and be able to keep track of All The Things. *headdesk*
