Mom :- "Why do you say can not go to school son?" ( Mother asked lovingly )

Son :- "The children and teachers at school are angry with me. They are scolding me.

Mom :- That's not to say son, you have to go to school tomorrow.

Son :- "No mom. I can't go to school." ( His mother was angry at his stubbornness. )

Mom :- "How would school work without you? You're the principal there, aren't you?"
