We see people like this everyday, to varying degrees. Some are blatantly obvious, like a politician who says one thing to get elected yet does the opposite once he is in office; while others are quite subtle, like someone who complains about the electric bill yet leaves lights & fans running when there is no one in the room.
Or one who complains about all the junk collecting dust, then complains when I have a yard sale to sell all that junk.
Or one who works only a 1/2 day, comes home and takes a nap; only later to complain that the spouse falls asleep on the couch after a full day of work.
