Thank you teacher Kurtfick, for your lesson. We did Callan 9, teacher Kurtfick let me answer first, even though I'm making mistakes. I felt it comfortable to answer with thinking with my words. It's my first experience in Callan Method to allow to use my words, I mean not only remember but also use other words that have same meaning in my poor English. Although it may not be the usual way to study Callan Method.
I put you one of my favorite teachers, see you tomorrow!
