They have no alternative but to think. One set of photos is of subdivision houses built in the 1920s, the other of subdivision houses built in the 1960s. The 20's houses sit relatively close to the sidewalk. Short walks lead directly to large front porches with furniture. Front doors tend to have lots of glass area.
Garages are detached, and some open on alleys.
There are no sidewalks. Instead of a porch there's a small stoop. Front doors have little or no glass. The walk from the front door goes to the driveway, not the street. Garages are attached.
