I love giving concrit but always keep it all to myself if I suspect the recipient can't take concrit well. Some people declare in blinking cruise control size 100 font that they want concrit. But once they get what they asked for, they get butthurt and threaten to stop writing/drawing forever if the "bullying" doesn't stop, which then turns everyone's guns on the poor person who was only sacrificing their own time to do what was asked by their favorite author or artist. Never again.
