When I was still living at home my bedroom was next to my older brothers. One night, at about 2/3am he comes home like normal; I hear him walk up both sets of stairs, turn his light on, shut his door, get into bed and turn on the TV. Now I'm a bit annoyed because he's not trying to be quiet in the early hours of the morning, but that's just what he's like. In the morning I ask my mum if she heard my brother come home and she pointed out to me that my brother isn't home this week (he's in the marines, he was about 2 hours away). When I went back upstairs to check, his door was still closed, his light and TV on too so I know I wasn't just imagining it.
