Grammar Rules & Patterns
The 'Snapshot' vs. 'Video' Rule
Preterite = Snapshot. Imperfect = Video.
Use the Preterite for a 'snapshot' of a specific, completed action (e.g., 'She opened the door'). Use the Imperfect for the 'video footage' of the background scene, ongoing actions, or descriptions (e.g., 'It was raining and she was feeling sad').

Imperfect (ongoing action) + 'cuando' + Preterite (interrupting action).
When one action was in progress and another action suddenly happened, the ongoing action takes the imperfect, and the interrupting action takes the preterite. The word 'cuando' (when) often connects them.
