Sue is shown to be a woman who does not shy away from speaking her mind. She has various altercations, particularly with dowager Lou Beale, who accuses Sue of having no community spirit. Sue's suspicious, insecure nature also provokes arguments between her and Ali, whom she often accuses of cheating. She has rows with other female residents, including Kathy Beale, Angie Watts, Debbie Wilkins, Mary Smith and Michelle Fowler, whom she suspects are trying to seduce her husband, although in truth, all that ever occurs is flirtation.
