Various NPCs have annoyed-lines when you keep pestering them, and the Garrison Mylune has one that is not just funny, but actually a quite impressive example of diplomatic skills:
#25 here:
"I am not the dryad you are looking for."
So the full meaning unfolds when it breaks the fourth wall and is seen as a popculture reference.
The line is as sweet as she is, even the tone easy to misunderstand, but the people who would ‘stick around for too long’ probably know Star Wars, so Mylune basically implicitly conveys that she assumes you are weak of mind and she is trying a jedi mind trick on you to make you buzz off.
And, beautifully, if you are not weak of mind but actually understand all this implication, then her sendoff is still working well. 
Furthermore, it is also a pun, because dryad sounds a lot like droid.
