Hanna is nine years old and is in third grade. She is nice and popular. She likes to go to school and learn new things.
Hanna can't wait for another day at school. During a break in class, children play on the playground. They are standing in line for a swing. One of her friends, Paulina, tries to skip the queue and get on the swing first.
Today there is art class. Kids bring various things: crayons, markers, pencils, sheets of paper. Hanna forgot her pencil case. She does not have things for art class. She asks Paulina to lend her a few pieces of paper and let her use her utensils.
Paulina refuses. Hanna is sad and angry. She is always willing to share with others in similar situations. She does not understand her friend's behaviour. Hania begins to resent Paulina.
Hanna wants Paulina to understand how she feels and is looking for a chance to get back at her for her actions. Hanna is upset with Paulina for not sharing and can't understand why she refused.
The teacher, Miss Honey, comes to class with the information that Paulina has a sprained leg and will not go to school for a week. It is necessary to visit her every day on the way home with notes from classes. He asks Hanna for it.
