Think of third person as you are watching it and telling everyone. She did this, he.said this. In some cases you could even do what they are thinking. One of my stories are in third person because I needed it and that's how I did it. I am watching them do things and I can even read their minds. Most of my first person stories have chunks of third as well. It sounds very interesting and I am sure people will love it.
Still in holiday. Extremly. And dogs.
Oh, and since I like the two bands in your username, I am going to check out this song. Hope your story goes.well.
