In our world there was once cultural, religious and ethical uniformity. People shared the same values, ideas and rules of behavior. In human relationships this was obvious and people could either be consistent with the common values or not. Now things have changed. We live in multicultural societies, where each individual has distinct values and rules of behavior. In human relationships you can no longer take anything for granted or demand anything from the other unless this has been explicitly clarified. In other words it is necessary to talk to each other and externalize what one wants or does not want, finding mutual consent or compromise. We can not blame anyone for not behaving according to our values, if we do not express them clearly and set them as conditions.
