Hi Diego Here's 5 versions. Each has a different meaning or emphasis, depending on where you place the word 'really': "nobody knows who I am, really" = to be honest, nobody knows who I am "nobody knows who I really am" = nobody knows the real person that is me "nobody really knows who I am" = nobody has a great depth of knowledge about who I am "really, noboody knows who I am" = in reality, nobody knows who I am "Really! Nobody knows who I am" = oh for goodness sake, nobody knows who I am

^^^Perfect explanation from Neal! There is nothing futher to add!
