I think the point here is that the solution to "John walked to the store" is turned inside out from a verb to a noun.  Create a noun (object) that is the result of the action performed.  Then you can add many properties to this object and talk about it.

This also helps when trying to use CRUD functions on everything (in an attempt to follow REST principles).  Inside of "door.enter()" you can "Entrance.create()".  Once I've done that, I can then talk about (apply properties to) an Entrance, because it is now a Thing.
