Hanna let herself in the front door as she always did and loped up the stairs, making no effort to be quiet.  When she reached the bedroom door she knocked once and opened it, letting herself in.  Once inside, she heard the water running in the shower and couldn't resist the urge.  She strode boldly to the bathroom door and opened it, poking her head inside.  "Sarah, your father is in the driveway!  You better get out of there!"  She closed the door and collapsed on the bed laughing.
