What changed and why

In my version of Nobita's story, it's Mimi, not Sam, who tells us what happens. Therefore it's Mimi we see searching for Sam, and it's Mimi who remembers the time when she was close to her brother.

Maybe, like Nobita, you're more interested in Sam's view of the events. But I wanted to highlight how, by changing the point of view from which a story is told, you can change the effect it has on the reader.

Remember, stories can be told from the viewpoint of:

One or more of the characters

The author, who just reports what the characters say and do - this means you won't write 'I said' or 'I did' but 'he said' and 'she did'

A mixture of the author and the characters
