Simple Past vs Past Perfect
When you’re describing many actions that happened in chronological order in the past, use the simple past.
For example:
When Charlie arrived, he sat down with Chloe, ordered a coffee, and they talked for a few hours.
However, if you want to specify an action was finished before another happened, use the past perfect.
For example:
When Charlie arrived, Chloe had already ordered a hot chocolate.
