I know full well that if Dad really wants to hurt himself , he 's going to do it eventually , and there 's nothing I can do about it . So I get a little bit angry when Jeff comes running to me to fix it because it 's like having him involved just puts one more burden on me . All those years he was uninvolved , I did n't try to force it on him , because I understood why you would n't want that on your mind . I resented that it all fell to me , but that 's just the way he is .
What may be a fact about the speaker ?
