Just throwing this out there: Do you ever find yourself identifying so much with your main character(s) that you find it hard to receive criticism on what they're like or how you've depicted them? How did you overcome that, assuming you have? Have you ever done a beta-read or a critique for an author whom you know or suspect might be a little too tied in with his or her protagonist(s)? How did you approach giving feedback on problems you've noticed, so as to avert the author's taking your criticism personally? Were you successful at getting your message across with no hurt feelings?
