I grew up in a one-story house with no basement. I always thought it would be so cool to have a second floor and stairs. It was just a case of wanting what we didn't have. Well, I have stairs now! Our house has three floors and a basement. Here's how having a four-story house works: there is always a three-in-four chance that the item you need is on a floor other than the one you're standing on. The result of this phenomenon is that my house is my gym!
