A mother would never by choice sleep in a wet bed but she would gladly do so in order to spare the dry bed for her child.
But you can wake a man only if he is really asleep. No effort that you make will produce any effect upon him if he is merely pretending sleep.
I was a coward. I used to be haunted by the fear of thieves, ghosts and serpents. I did not dare to stir out of doors at night. Darkness was a terror to me. It was almost impossible for me to sleep in the dark, as I would imagine ghosts coming from one direction, thieves from another and serpents from a third. I could not therefore bear to sleep without a light in the room.
