It brings everyone together, while humiliation tears them apart. In a society torn with humiliation and insult, humour is like a breath of fresh air. It should be coupled with care and concern. It can keep the spirit high, yet if overdone it leaves a bad taste. Humour without wisdom is shallow. Humour without sensitivity is satire—it comes back to you with more problems. It is used in the following ways.

Humour The intelligent To shield against humiliation

Humour The cruel To insult others

Humour The irresponsible To escape from responsibility

Humour The fools Seriously

present in the world”?

ii) The cricket says, “oh! What will become of me?” When does he say it

and why?

iii) What were the warning signs that both Tilly and her mother saw?

iv) In what ways did the British officers exploit Indians?
