From a recent subject of a story:
GREAT JOB! I think you covered every important aspect and issue. You showed empathy, humor and in depth research. I don't remember you writing anything down and our time with you was comfortable, honest sharing.....not interview-esque!
I'm very impressed by your style!!! Congratulations and thank you for spreading the word!!!!
