He hadn’t left his house
I had finished dinner
She had started to sing
He hadn’t broken up with his girlfriend
When the bus arrived,
At the moment your boyfriend arrived,
They hadn’t fully arrived at the classroom
My parents had gone
I had ordered Chinese food
We hadn't cleaned
you had already left.
when my parents told me there was dinner at home.
the room before the guests arrived.
when my mom called me.
when it started to rain.
I had already taken a taxi.
when my sister came to my room.
when he started dating another girl.
when the professor started to reprimand them.
and the karaoke wasn’t installed yet.
