Google released its list of the most searched people of 2013 on Tuesday, and not surprisingly, Miley Cyrus received the coveted No. 1 spot.
If first person is someone telling you his or her story, and second person is you being told how you should do something, then third person is more like a camera recording events. That's not to say it's necessarily an objective point of view. A third person narrator can be highly subjective.
First person: First person is used when the main character is telling the story. This is the kind that uses the I narrator. Second person: Second person point of view is generally only used in instructional writing. It is told from the perspective of you. Third person POV is used when your narrator is not a character in the story. Third person uses the he/she/it narrator and it is the most commonly used POV in writing. Or, simply search how to tell point of view on google. What's written above was taken from the first result I got from this search.
