Feeling guilty towards your parents?

I remember two stories from young male clients about feeling guilty towards their parents (father) because of the choices they want to make in their adult life. I thought ...very interesting in this time and age.  So I asked them:
“How come you cannot talk about this subject with your parents? “
They said: “Fear for disappointing them and quilt for not being the perfect son.”
When I asked more questions, I heard that most of their thoughts and fears were not real but felt real according to their assumptions. And what they had experienced as a child.
But now we are adults...Unfear yourself.... Let’s learn to talk more as equals about our mutual expectations. And check our assumptions by being explicit in our questioning. "maybe you do not like what I want to share with you but at this time in my life I have to make this choice, I hope you understand.
