Because parents don't give their children too much money, sometimes children don't have enough money, so they will try their best to ask their parents for money. First, the child gave the pencil-box to his classmates and said that the pencil-box was missing and the teacher couldn't find it. At this time, parents will think that the loss of the pencil case will affect their study, so they will give money to buy one for their children, and then the children will have money to eat, drink and have fun. They will also share some money with the partners who take care of the pencil case, drink, eat and play video games together. Finally, I secretly used the original pencil case and took my partner's pencil case home, saying that it was my new pencil case, and I spent a lot of money on the pens inside.
