Simple past or Past perfect? - 1

We use Simple Past if we give past events in the order in which they occured.
However, when we look back from a certain time in the past to tell what had happened before, we use Past Perfect.

Do you just want to tell what happened some time in the past or do you want to tell what had happened before/up to a certain time in the past?
