Past Simple vs. Past Continuous

The past simple commonly presents a past event as completed or bounded, while the past continuous presents an event or temporary situation as in progress around a past time. The difference is often one of viewpoint, and the two forms frequently work together in the same narrative.

Quick answer

Use past simple for a completed or bounded past event; use past continuous when you view an event as in progress or as background around a past time.
