A boy and a girl were insanely in love with each other. They decided to become engaged. And that’s when presents are always exchanged. The boy was poor – his only worthwhile possession was a watch he’d inherited from his grandfather. Thinking about his sweetheart’s lovely hair, he decided to sell the watch in order to buy her a silver barrette. The girl had no money herself to buy him a present. She went to the shop of the most successful merchant in the town and sold him her hair. With the money, she bought a gold watchband for her lover. When they met on the day of the engagement party, she gave him the wristband for a watch he had sold, and he gave her the barrette for the hair she no longer had.
