Verb Tenses
Past perfect
The earlier past event takes had + past participle.
Why this happens
Past perfect (had + past participle) shows the earlier of two past events, but writers use it whenever the past is mentioned, even when sequence is already clear. Others forget it and leave ambiguity about which action came first. It matters for narratives, reported sequences, and cause before effect. If both events are simply in the past with no ordering problem, simple past is enough.
