As I am bent over taking out the milk , I hear footsteps pass the kitchen entrance , in the living room , and then his office door open . It was latched shut and I heard what sounded like the door knob turning and then the door opened all of the way . I thought it was my husband getting up during the night as he normally does and going into his office due to his insomnia . I look into his office and do n't see any cats around in there . I go back to bed and ask if by chance he just got up , opened his door and then went back to bed .

Question: Why did I go back to bed ?
Answer: Because I heard footsteps pass the kitchen entrance .Because I heard footsteps in the living roomBecause I did n't find anything out of the ordinary .None of the above choices .
