In any kind of relationship we can make the assumption that others know what we think, and we don’t have to say what we want. They are going to do what we want because they know us so well. If they don’t do what we want, what we assume they should do, we feel hurt and think, “How could you do that? You should know.” Again, we make the assumption that the other person knows what we want. A whole drama is created because we make this assumption and then put more assumptions on
top of it.
