I always say that nobody is obliged to do anything or to explain anything to me. And I am sure that is an indicator of an attitude: I won't explain only when a person is not able to understand at all or it is too painfull to me. Or if I do not care at all. Any other time I don't want to a dear one to worry or wonder, to suffer from ignorance. So how should I react to complete ignoring of questions which are so important to me? I can only repeat again and again that noone is obliged.
