person A: I had a secret and went to my mother to confide in her_comma_ as well as get off my chest. I know she would never betray my secret and can always count on her.
person B: I am so happy for you that you have someone you can trust so completely.
person A: Yes_comma_ I sure do! There aren't many people you can feel that way with and I am so grateful!
person B: Hopefully she knows how much this means to you.
