What they say/What we hear

Yesterday Libby and I had this conversation:
L: "Need Pornography"
Me: Blank Stare (and in my head: "How does she know that word? Who taught her that? Where could she have possibly heard that??!")
L: "Need Pornography"
L: (A little louder) "Need Pornography!"
Then she went to the baby gate at the bottom of the stairs and shook it, trying to get up to her bedroom.
L: (Loud and frustrated) "Need Pornography!!"
FINALLY a lightbulb went off in my mind....
Me: "Oh, You want Pooh Number 3?!
L: Big smile
Thank God it was only a request for one of her many Pooh bears!
