I was pacing around, contemplating, and I looked outside and noticed the single mom who lives downstairs getting into her car, with her three kids (one a baby. Whenever I see her she looks really tired, stressed out and unhappy. Don't blame her), and I realized I don't really know any of the people who live in the same building as me, and then I was thinking about how that's sort of sad, how we all pretty much live together and don't communicate at all.

Do you know your neighbors? Are you friends with them?
