So what among the terrible flaws your adult child has bother you the most? Granted the whole package makes it unbearable but is the flaw yo u hate dislike or whatever you wanna name it about you difficult child? For example for mine is his lack of ambition to improve himself basically he does not do anything without being forced be it me or his mother, society and how the world works. He does normal things not because he wants but because other want. He does not care for him which yeah annoys me so much. Which makes the question how can he care about what others so much that he does things for them and not for him? Is it not you must learn to love yourself before you love others? What is the flaw that bothers you the most?
