I (1) opened the kitchen door and Alan and Liz (2) came in. They (3) sat down, and I (4) made them both a cup of coffee. This is what Liz (5)  was telling me: We (6)  were sleeping in our bedroom when we (7) heard a loud voice coming from your kitchen. So Alan and I (8) decided to investigate. We (9) came to your garden, but couldnt see any lights on. People (10) were talking in the kitchen, though! So, we (11) thought that we should call the police. Just then, you (12)  turned the light on in the kitchen, and we (13) saw that everything (14) was all right. So, we (15) were standing in the garden wondering whether to say hello to you or not, when you (16) opened the kitchen window and (17) said hello to us! That (18) explained almost everything. But I never (19) found out why the TV came on in the middle of the night!
