• In conditional sentences, past perfect shows unreal past situations.
• Don't overuse past perfect - only use it when you need to show clear sequence of events.
Pro Tip
Think of past perfect as the "past of the past." Ask yourself: "Did this action happen before another past action?" If yes, use past perfect. If no, use simple past.
