Carter opened the door and entered the silent house. His entire family had persuaded his hardworking grandparents to take a much-needed break. Carter had promised his grandmother that he would water her precious plants during her absence. He looked around at the familiar surroundings and smiled fondly, remembering all the fun he and his cousins had had there during their childhood. Carter thought that it would be a nice surprise for his grandmother if she found some beautiful flowers in her garden when she came back from the trip because he knew she loved flowers. He watered the plants in the garden and returned home.
That night, over dinner, he told his mom about the surprise he had planned for his grandmother. His mom nodded and also suggested that they repaint the entire house. Carter and his mom decided to involve the whole family, so Carter immediately called up his cousins, who said they would be glad to help. Carter reminded them that they had only two weeks to get the house ready.
Carter and his cousins gathered at their grandparents' house every evening. Apart from applying a fresh coat of paint to the entire house, they also repaired the leaky faucets and dusted and polished everything in the house until it sparkled. Carter and his cousins went to the plant nursery nearby and chose some violet plants for their grandmother's little garden. They mowed the lawn, weeded the flower beds, and planted the new violet plants. Soon, the house was ready for their grandparents' arrival.
On the day of their arrival, all the family members gathered at Carter's grandparents' house to welcome them. When the grandparents arrived, they were overjoyed to see the freshly painted house and the whole family under one roof. Grandmother hugged Carter and his cousins when she saw her garden and thanked them for the violet plants. The family was moved to tears and decided to have more family gatherings.
