Space and Time
The fact that we call things things is a social construct, as language is socially constructed.

Space, according to Dourish, is NOT an objective thing. Our understanding of space and where they are can impact our interpretation of that space.

How time/space compression, or globalization, affects people differently. How would a homeless person interpret a trash can vs. how might a non-homeless person interpret that trash can?

Part of the way we understand a given space is how we can collaborate and use it.

Even though we can have a bunch of different maps, or images, to describe a single thing (e.g. a map of the U.S.), by internalizing these things, we then interpret and take things from a personal point of view.
