Interview Check

I am planning on interviewing a family friend that has been in the psychological field for quite some time and has experience with child abuse and these kinds of situations. She has had lots of experience and I know that she is a very helpful person that would help answer any doubts that I might have. I plan on asking: How do you make these children trust you? Has there ever been a time when a child does not open themselves to you? What do you think is the most difficult part of this career? Do you recommend this career choice?
