There's no need for a Top 10 list of the potential drawbacks. I assume most of us know about loud, bathroom-hogging roommates whose visitors tend to be foul-smelling, braying jackasses.
But that's not the whole picture.
If you are extremely fortunate, you might encounter people like Ron and Marsha Feller on the other side of the drawn curtain.
A few months before my father died here in Spokane in 2007, he shared a room with Ron Feller, a teacher and artist.
At that stage of his life, my father was a challenge to deal with, to put it mildly. He had lost the ability to recognize the problem in loudly calling out for assistance with some non-pressing matter at 2 a.m. And then, after getting some exasperated attention, doing it again at 2:17. Et cetera.
But Ron and his wife, Marsha -- who spent hour after hour in the room, treated my dad with superhuman patience and compassion. My mom and I were awed by their generosity of spirit. We still talk about it.
Four years later, Marsha and Ron keep in touch with my mom, just to make sure she's doing all right.
A lot of people talk about what great people we have here in Spokane. But there's nothing like seeing a couple of them in action to make you a believer.
