I love these people and know my work is better for their eyes.
But there are always those people in critique groups who don't really want feedback, just glowing praise of their genius. The ones who rather than accepting the critique, and acknowledging that maybe their work isn't flawless, will argue about why they're right, why the choice they made was the right one.
These people frustrate me. Why put your work up for critique if you don't actually want to improve your work? Just write for yourself and enjoy your own voiceless ramblings through plots that lack tension and characters whose behavior elicits no sympathy. Don't waste my time if you don't want my opinion.
I take a lot of time over my critiques. I read chapters several times through, giving every line and turn of phrase careful consideration. If my opinion isn't wanted, why did you put the book up for critique? If you're not willing to admit there are flaws in your work, why are you asking for help with it?
If you want glowing praise, give your chapters to your mother instead.
Do you have people like that in your critique groups?
