It was ten o'clock in the evening. Peter sat / had sat down on his sofa and thought about the day. What a busy day it was / had been !
This was his first night in his own flat. He lived / had lived his entire life in the family home, and now for the first time, he was / had been on his own.
He sat surrounded by boxes that they didn't manage / hadn't managed to unpack during the day. It took / had taken months to get all his things together. His mother was / had been very generous, buying him things like towels and mugs.
He went / had gone into the kitchen and got / had got a beer from the fridge. He suddenly felt / had felt very tired and yawned. No wonder he was / had been tired ! He was / had been up since six o'clock in the morning.
He decided / had decided to finish his beer and go to sleep.
