The difference between the past simple and the past perfect
When the events of a story are told in the order in which they occurred, the past simple tense is used:
I
missed
the last bus, so I only
got
home at about 6 o'clock. I
was
really tired, so I
took
a hot bath. Then I
made
some dinner and
watched
a film. At 10, I
was
in bed.
However, if the events are told in a different order or there are references to an earlier time, the past perfect tense is used to express the earlier events:
I only got home at about 6 o'clock because I
had missed
the last bus. I was really tired, so I took a hot bath. Then I made some dinner and watched a film I
had borrowed
from my friend Sheila earlier that week. At 10, I was in bed. It
had been
a long day.
