Darking Bogs

We took a walk this afternoon hoping to put James to sleep.  There is one house up the road with a dog that has a mean sounding bark. We had a conversation that went something like this.
 Lea:  "When we get close to the house with the darking bog I want to turn around if it comes out."
Mom:  "The darking bog?"
Lea: "Yes I don't like the darking bog.  We should walk back to the creek if he is out."
Emma:  "Did she just say the darking bog?"
Lea:  " How close are we to the darking bog?"
(By this time we all started laughing)
Lea:  "What is so funny?  I don't like the darking bog?"
More laughter, Lea included.
Emma: "Do you know why we're laughing? You said the darking bog."
Lea:  " Yeah, I'm afraid of the darking bog!"
It took a while before anyone could stop laughing enough to point out what she was saying.
