carpet is badbadbad. When I was renting with carpets throughout, I always had problem with fleas. Now that I only have hardwood, aside from the stray bite I don't really have a problem.

Speaking of concrete, when I renovate my kitchen, I really want to just have concrete with that acid finish. I hate grout, and cleaning would be a breeze. The only problem is I've yet to see one that's actually decent looking.
