Somsak tells Anna and Nok about his trip to the site last week.

Somsak: 'When I arrived at the site on Monday, the workers had already left. I had told them to wait, but they hadn't received my message in time.'
Anna: 'What happened next?'
Somsak: 'I called the site manager. He said he had sent someone to check the foundation the day before, and it had passed inspection. So at least that part was good news.'
Nok: 'Had you visited that site before?'
Somsak: 'No, I hadn't been there before Monday. It was my first time, and I hadn't expected it to be so far from the city!'

Anna nods. 'You used past perfect really naturally there. We use had + past participle for an action that happened before another action or time in the past. Compare: I arrived at the site — simple past, the main past event. The workers had already left — past perfect, this happened earlier, before I arrived.' Somsak thinks for a moment. 'So it's like a past-before-the-past?' 'Exactly,' says Anna. 'It helps listeners understand the correct order of events.' 🔊
