Before it becomes unrealistic? See, Heridon (who is hard of hearing), when he was in his elementary/middle school days, once attended a local school for the deaf and blind. From 1st grade to 8th grade, had to contend with a really snotty teacher who showed her true nature with her students (in private, of course, not wanting to loose her job with superiors. She's a crafty, manipulative, controlling *****). When he had her in his 7th year, he experienced the worse from her. Since the school also had students who were not deaf/blind, he had the misfortune of being the only deaf kid in her class and thus, was picked on by her. Now he's in his early/mid-twenties and his deaf cousin now attends the school. Worse, the teacher still works there. (Remember, she's pretty clever and knows how to keep herself out of trouble.) Though he doesn't have to deal with her on a daily basis anymore, he still holds a grudge against her. But is it realistic? He hadn't been in that school for almost a decade. I think it's okay since people IRL can hold a grudge over something to their grave. But would that include a grudge over a horrible teacher they had back when they were a child? I figured that could be a good character flaw for him: An inability to let go of the past and all that, so that's why I have him holding a grudge for that long. Thoughts?
