Jackie’s father didn’t allow him to stay in the playground after school hours. His father said he must come straight home. But one day Jackie forgot about it and came home very late, very dirty and very tired.
– Look here, – said his father angrily, – didn’t you promise me that you wouldn’t stay out and play games?
– Yes, father, – was the answer.
– And didn’t I promise to punish you if you stayed?
– Yes, father, – said Jackie, – but as I didn’t keep my promise, why should you keep yours?
