Summer holidays
This summer, Anna visited her grandparents who live in the countryside. She stayed there for two weeks and had a wonderful time. Every morning, Anna helped her grandmother in the garden. Together, they watered flowers and picked fresh vegetables. In the afternoons, she went swimming in the nearby lake with her cousins. They also rode bicycles along the forest paths and had picnics under the big oak tree. In the evenings, the family gathered to watch the sunset and tell stories.
