Point Of View In Narrative

There are 3 types of point of view:

1) First Person

2) Second Person

3) Third Person

A First Person point of view is when the word "I" is used. This is commonly used as it is easier. It is about observing the character from his point of view
A Second Person point of view is when you use the word "You". It is not from one person's point of view anymore, but it is from the person's and the person beside him's point of view. This is not commonly used.

A Third Person point of view is when you are using the word "We". Whatever you write is from a general point of view. There is no "I" or "You" in the story. Characters are given names and not like 'me' and 'I'. We must be careful when we write in this point of view as we are not the character inside the story. So we cannot change the name form Tom to I as i am not Tom in the story.
