I opened the kitchen door and Alan and Liz came in. They sat down, and I made them both a cup of coffee. This is what Liz told me: "We slept in our bedroom when we heard a loud noise coming from your kitchen. So Alan and I decides to investigate. We came down to your garden, but couldnt see any lights on. People were talking in the kitchen, though! So we thought that we should call the police. Just then, you turned the light on in the kitchen, and we saw that everything was was all right. So we stood in the garden wondering whether to say hello to you or not, when you opened the kitchen window and said hello to us!" That explained almost everything. But I never found out why the TV came on in the middle of the night.
