The history of urban planning is one of the attempts to manage publicspace in ways that build sociality and civic engagement out of the encounter between strangers
This idea is interesting and also surprisingly refreshing. In a sense, individuals, children, and even parents are now actively teaching and practicing strategies to avoid encounters with strangers. If a stranger walks up to you and starts talking many people will not even take an ear bud out and just continue walking. Whether this is due to fear or rudeness, people are seemingly much more reserved in public spheres today.
