Hitting a wall

Every night around 6 o'clock I hit a wall. My eyes get really heavy and I just want to lay my head down somewhere nice and soft and quiet. I really have to pull myself through for that last hour before the littlies bed down at 7. Last night I just needed to stop for 30 seconds. I rested my head on the armrest and sighed, "Mummy's hit a wall". The Rooster was quick to reply,"No hitting walls Mummy, or Daddy will take your toys". Out of the mouths of babes. Daddy must be a mean old thing!
