The rain had stopped before I went for a walk. My mother had returned home before I did my homework. We had met in the street before we went to the park. They had packed their things before then they started. I had switched on the TV set before I had dinner. He had returned home before the guests left. We had came to the cinema before the film began. I had read the book before I saw the play. They had lived here before they moved to another place. We had played a game of tennis before we went to my place.
