You will be given a situation. Come up with a cause and a consequence of the situation, then make a grammatically correct sentence using the past perfect for each, either individually or with your neighbour.
Example: I had a fight with my sister last month
Cause: I had a fight with my sister last month because she had borrowed my bike and scratched it.
Consequence: I had had a fight with my sister, so I didn't talk to her for three days.
