Charlie took his wife, Karen out for a dinner at a musical club.  This relationship is new and exciting for both of them, as this is Charlie's second marriage.  Karen feels the need to impress Charlie and constantly smiles, although she really does not even enjoy the musical entertainment at the club.  The two dine in fancy clothes and have superficial conversation amidst the entertainment in the background.  After dinner, the two will walk through the streets of the city, holding hands.  They will talk about how much they both "loved" their evening together.
