Time is difficult to explain, yet we deal with it every day. All people talk of time as "motion on a space," and think of time as linear.
- Durations are talked about using size ("a short weekend").
- The passage of time is treated as a movement. ("the week flew by").
- We think of events as located at different positions on a path - internally as "the week ahead of us" and externally as "a reception follows the ceremony."
