I'm not a huge fan of pets. And there are plenty of reasons that I won't go into here, but I do like fish. I like them because they are cool to watch swim, you can't get super attached to them (they pretty much have one awesome dazed expression), they don't shed, and they won't beg for food while you are sitting at the table.
So if we end up getting a pet ever, it'll definitely be a fish. And that fish will live here: The Fish Condo. The benefits of living small are touted in all sorts of places these days: The Not So Big House, New Urbanism, the housing crisis--all making people rethink their attachment to football field size family rooms. Our philosophical fish will take this to heart, and dream big dreams in his tiny pond.
