Who gets on your last nerve? What do they do that bothers you so much? Why do you think they do that? Now, what is an endearing quality you have? My ex! he was always picking his fingernails/clicking it drove me up the wall and down the other side. He did it because he knew it annoyed me. Uniqueness, wittiness, charisma, loyalty, honesty, (sorry you said one, but couldn't decide)
