A couple had separate bedrooms and their daughter alternated between them to share the room. In order to protect her from the finer aspects of adult life - you know.. sex - they invented a secret language. They decided to call it 'sending a letter'.
One day, the little girl went into her mother's bedroom and told her that Daddy had said that he needed to send a letter and was she available to type it?
The girl tool a message back to Daddy that said, "sorry love but the typewriter only has red ink at the moment"!!
A few days later though another message read "It's OK, the typewriter has been fixed and I can type that letter for you now - with pleasure"
The little girl, now feeling quite tired, returned to her mother and told her that daddy said "Thank you for the offer but as the letter was somewhat urgent, I wrote it by hand"
