Yes, and it's either a British person or Morgan Freeman doing the narrating.

Creative and cleansing. Other ways to do that too. Writing, poetry, music, singing. A great trait

Hahaha, that's so funny. I do the same thing. It makes sense to do that. Personally I enjoy writing a lot, so narrating my actions and/or thoughts is a great way of practicing my writing style.
