Easy formula for Changing Narration
 

Dear friends...........!
There is a formula regarding direct indirect:

S O N
1 2 3

S: subject
O: Object
N: No change.

It means that 1st person pronoun used in the reported speech (which is in inverted commas) will be changed according to the subject of reporting speech.

And 2nd person pronoun used in the reported speech (which is in inverted commas) will be changed according to the object of reporting speech.

And 3rd person pronoun will remain unchanged.
