Seashell
Fleur Weasley had always wanted to live by the water when she was younger. So when she and her beloved husband Bill Weasley were looking for a house and he had suggest Shell Cottage. Once they entered the house to look at it, Fleur instantly loved it. She turned to Bill and said, "Zis is peefect Beel!" She kissed him on the lips and they moved in to the house in the next week.
Once they moved in, Fleur would go out to the beach and take a walk once a week. Every once in a while Bill would join her. On those walks Fleur would look for seashells. The seashells reminded her of her home in France. With her parents and little sister, Fleur used to go to the ocean side once every two months and they'd find the most beautiful seashells to take home with them. It was a tradition that they'd all get at least one. Soon after starting the tradition, her family had a collection of seashells that would be a reminder of the ocean side, and the good times.
Having the beach so close to her was a dream come true to Fleur. She had a place where she already had a collection of seashells, and she was with the one she loved.
