    Context - The past perfect tense is usually used in stories, because the events in the stories happened in the past, and the conversation in the stories that happened in the past are about events that happened before that:

    Kyle- I have a story for you James! I was at the beach and I saw our old friend Paola. She said she ____________ (go) to Africa. Remember how she was afraid to even leave her home? She __________ (marry) a king there and offered to take me on his boat for a fishing trip.
    James- Why didn't you go? I remember when we were kids you _______ always ________ (tell) me that you always wanted to go fishing in the ocean.

* Don't let had and have of the perfect tenses get confused with the verb to have.
