My sister has a bad habit of going in peoples rooms without asking. She also has a bad habit of leaving empty cups everywhere (I swear she’s 50% tea). I hadn’t been in my room for a while, and when I went into it I saw an empty cup of tea on my couch. I walked over to where she was (in another room) asking if she by chance has been in my room. She tried to play innocent, indignantly asking why she would be in my room, until she looked up and saw the empty cup in my hand Her reaction was funny, she just went oops and went to put the cup away.
