I find it a commonly occuring theme that people blame themselves for not speaking up when a friend or relative acts in a way that is obvious to an outside observer to be ruinous to their own well-being. If your friends/family are too afraid to speak up, then who will?
In balance, I find it an equally occuring theme that one believes their friends are blaming one for ruining their own lives without offering anywhere near enough support and loving advice.
In my view, life is a balancing act for all of these types of issues, but I find it is very obvious to an outside observer where ones life is dangerously out of balance, while one is often too busy or too obsessed with other aspects (which are not out of balance) to notice.
Truth be told, I am not really sure where my life is out of balance, and the only "advice" I have been getting is that I have too many children to adequately meet their needs (to achieve excellence?) - That my autistic boy, is in part that way due to a lack of time devoted talking/interacting with him - that my work/family balance is tilted too far one way or the other (depending who I'm talking to)
If the viewpoint is framed as "loving advice" rather than "blame for what went wrong" I am encouraging more friends/family to give me advice, and equally, that I am not showing enough care if I don't mention something that is obvious to me about them, if it is framed properly. Email is the best avenue to mention these things.
