supper l (watch) television for a while and then (decide) to go to bed
early. I just (go) to lie down when I (hear) the sounds of men's voices,
talking quietly I (be) terrified. (ge) out of bed, and (creep) downstairs.
The voices (come) from the sitting-room. l (tremble) all over. I slightly
(open) the door and then (laugh) with relief In my tiredness I forget) to
turn off the television...
