In the indirect speech, the above conversation can be written like this.
The headmaster asked Swami why he had not come to school the day before.
Swami replied respectfully that his mother had been suffering from fever. The
headmaster retorted that he did not believe his words and added that he always
said something or the other to escape from school. Then Swami replied
respectfully that he was speaking the truth. Then the headmaster told him that he
would go to his house the next day and talk to his parents.
As you can see, while converting the direct speech into indirect speech,
the words in the bold are added to express the feelings, emotions, attitudes of
the speaker and the sequences of the actions.

Read the following imaginary conversation between Swami and his father. Swami’s Father : My dear Swami, why are you looking so dull? Why haven’t

you gone to school today?

Swami : Daddy, I don’t like the school. The headmaster beats me every day.

Swami’s Father : Why does your headmaster beat you every day without any reason? I’m sure you must be causing a lot of nuisance in school.

Swami : No Dad. The headmaster beats all my friends in the same way.

Swami’s Father : OK. What do you want to do now? Don’t you go to school and continue your studies?

Swami : No, Dad. I'll join some other school.

Now change the conversation into indirect speech.
