Lena and Oskar have slept in and are looking forward to a free Wednesday at home with their grandma. They decide to be very well-behaved for once and to bring a lot of joy to the adults. Will they succeed in putting their plans into action, and will Mom and Dad be thrilled? "A Day of Being Good" humorously tells the same story from both the children's perspective and the parents' viewpoint. It is a loving book about the sometimes challenging coexistence within a family. Indrek Koff and Ulla Saar are the stars of the children's book scene in Estonia. "A Day of Being Good" was chosen as one of the five most beautiful Estonian children's books of the year.
