1st pov situation:A situation like this can be so real that indeed just happened to me the other day. I was writing something but my mind was in other parts, so I was not focused on the task at hand. In the beginning, I had the idea and how to develop it. But then it came some distractions and my mind started to wander. I finish my writing but the other mistake was that I did not double-check it. The result: a very bad work that made no sense at all.
The referring to one self with pronouns such as "I" or saying phrases such as "he told me" along with narration of personal thoughts (but that is contextual)
