Eliminate the bolded mindset.
It's hard too. This girl went to a private secondary school here and works in Hollister (and people say you have to be really good looking to work there?) so definitely she probably has a boyfriend anyway.
Just keep being yourself and bring out the usual charm once in a while. Whether you get her or not is irrelevant at this point. It's just to the point where she respects (and trusts) your presence and enjoys having you around
Will just do that then.
