I've been a member of three critique groups. I've met some really nice folks who still stay in touch, but Oh my gosh. I don't think I'm alone in this. You critique a story and send it back, you know the person on the other end is either going to balk or see the light. I do both. I balk, then I see the light.
You spend hours sweating over each and every word you write and put it out there for someone to, dare I say, criticize. That's what critique means. It's a humbling experience.
After the decadent ice cream binge, the denial, and the stomping of feet, you finally have to either reject or accept, sit down and put the advice to use or not. It's always been your choice and it's always going to be painful. But in the end, goshdarnit, you turn out to be a better writer and a better person, so sock it to me, I need improving.
