Dory is your little sister, she is only four years old, and she is very special. For example, her first word was not "mama" or "dada", but "mora". She loves money very much - even more than your parents love you both.
You were very worried that she might say something wrong to her peers and they would bully her, because children are very cruel these days. But on her first day at kindergarten, Dory decided to sell her toys for money. Unfortunately, her plan did not succeed, because none of the parents gave their children money for kindergarten.
Dory was very upset about this, and the parents of the other children were especially dissatisfied. They began to complain to your parents that this had a negative effect on the children and that their children were now asking them for money.
