Roleplaying Ideas: Someone still becoming aware of this trait may be constantly worried or concerned about others whom she sees the future of, this stress will only be magnified by the fact that she is powerless to help them; not that she won't try. More experienced individuals may become bitter or exasperated with people not listening to her, feeling agitated at the fools surrounding her; no matter how many times she warns them they never listen.
