On Saturday afternoon, Rod and Jing arrived with Jack, their luggage and some beer. They were going to a party in the evening so they had bought some beer on the way to my place to take with them. They invited me but I was too tired to go. I just wanted to stay home and watch a movie on television. I gave them a key when they left, and then went to bed at about 10 o’clock. I heard them come in at about 11pm and go to bed upstairs in the spare room at the back of the house.
