On Valentine's Day, Ann and Donald share meaningful gifts with each other. She presents him with a tie clasp, while he surprises her with a beautiful pair of diamond earrings they both admired at Tiffany's. Ann feels anxious about wearing them. When Don firmly encourages her to wear the earrings for their dinner and dancing date, one mysteriously goes missing. To make it right, Don purchases a replacement earring and leaves it at her apartment. Not wanting to let Don down, Ann decides to buy her own replacement earring as well.
