Brothers are the best friends (by Joan Bauzà)

There was once a 10 year old boy named Paul and he had a sister called Martina. Paul always wanted to play with his sister because his friends did not want to be with him, but Martina was always playing with her best friend, Laura. One day, Paul went to buy biscuits and he met a boy and they became friends. One morning, Martina went to Laura's house and she found a sign with the word "SOLD". Laura had moved and she returned , Martina felt really sad because now her brother no longer wanted to play with her.
