Why Such a Large House?

While not large to some people’s perspective, this house is larger than I need it to be for my current lifestyle. I am a single person, and this is a 3BR house. With that in mind, there are 2 bedrooms that are likely to not be used. However, the good thing about this house is a just in case I came across Ms. Right and she has a couple of children. Even though the house is narrow, it is 62′ long, and have a basement, and second floor.
