Okay, that's a bit harsh, but to a certain extent that's what you have to do when you audition for someone. It's a fine line - you want to pull the person hearing you in, just like with any audience member, but at the same time, you can't worry about whether or not they like it.
Of course, you are always walking this line when you sing. However, when you sing for an audience, this is diffused across a larger number of people, so it is easier to imagine that the crowd is "pulling for you". When you are just singing for just one or two people, it is easier to feel that "I'm being judged".
When you audition, you are, of course, being judged, but nevertheless, most of the time, those of us hearing you, want you to do well, so try to concentrate on that! That may help that audition feel like a performance, which in turn, will make it a better audition.
