When I came, they were eating my watermelon (ewentualne "they had already eaten")
We were reaching the station when the rain started.
I remembered that I had left my umbrella at home.
When we arrived at the party, Tom had already gone home.
After Ann turned off the light, she closed the door.
My friends showed me the pictures which they had taken on holidays.
The wind blew away the paper materials that I had left on the table.
