A newlywed couple arrived back from honeymoon to move into their tiny new flat.
"Care to go to bed?" the husband asked.
"Shh!" said his blushing bride. "These walls are paper thin. The neighbours will know what you mean! Next time, ask me in code - like, 'Have you left the washing machine door open' - instead."
So, the following night, the husband asks: "I don't suppose you left the washing machine door open, darling?"
"No," she snapped back, "I definitely shut it." Then she rolled over and fell asleep.
The next morning, she woke up feeling a little frisky herself, so she nudged her husband and said: "I think I did leave the washing machine door open after all..."
"Don't worry," said the man. "It was only a small load so I did it by hand."
