Most of the books I’ve read, and have written, have the MC being amazingly observant. I know why we do it- how else would we get across all those juicy details? But is it real?
How many of us have the observational skills of Sherlock Holmes?
Even though I pride myself on being a people watcher, I know I miss way more than I catch. To get around this, I usually have two MCs, which, I feel, help the story stay authentic and real while at the same time propelling it forward. It even gives the opportunity for some misunderstandings, which always helps with the tension level. But that’s just me; for some reason I have to keep it as real as possible. I think that’s because, in my own mind, it is.
