When should I use the past perfect instead of the past simple?

Use the past perfect to show that one past action happened BEFORE another past action: "When I arrived, the meeting had already started." If two past actions happen in sequence with "and" or "then", past simple is enough.

Is past perfect required after "before" and "after"?

No. With "before" and "after", the time order is already clear, so past simple is often acceptable. Past perfect adds emphasis on the earlier completion.

What Is the Past Perfect Tense?

The past perfect tense is used to describe an action that happened before another action in the past. It is formed using had + past participle. Example: She had finished her homework before dinner.

The past perfect tense is often used with the past simple tense to show which action happened first.
