You can always tell when a bell has a crack in it. It does not ring true.
And you can tell when a girl or boy has a crack somewhere in his character. He or she does not give a clear ringing sound. One of the worst kind of cracks is dishonesty.
You can't trust that kind of person. He always has to be watched.
What a horrid kind of child that is, from whom you dare never take your eyes!
But when you see a real honest girl or boy, how you admire the sight.
They will not cheat. They play fair. They are true sports. They won't take advantage of you when your back is turned.
You know how even in school games you like a real sport, who plays the game and obeys the rules of the game.
You can't have a game with any other kind. He spoils everything and you can't have real life with a cheat. He spoils the school and disgraces a house.
More than that, an honest person will not take what does not belong to them. A lot of girls and boys forget the difference between "mine" and "thine."
Then when they grow up they spoil society, and if they go far enough, they become that awful thing, "a thief."
