What Is the Point of Coaching?

In the first feedback meeting I felt quite nervous little bit uncomfortable and as a result like my normal coaching style or my normal way of coaching didn't flow. In the second conversation I was I was able to be a bit more natural so could it have been something else? It's just not 10 doesn't tend to be how I do it but what I'd done is just had loads of nice friendly chats and you know talk a little bit about what the point of coaching is from  my point of view.
