I'm not always wrong, nor am I always right; same goes for pretty much everybody else. We're human, so we are all alike in terms of this, regardless of how you might put it. Don't mind when others correct me, but it usually depends on the way they actually execute it. If they give good explanation and reasoning behind their statement, then that's perfectly fine. If they straightly go ahead and say "this is not how you do it, etc. etc.," then I might wind up getting a little... annoyed. :( I would accept it either way, though (if they have some good point), but in my opinion, former is the best way to go about these kind of stuff; usually, that's how I do it, because I just don't want people getting upset. I'm very sensitive when it comes to how others think of me, so I try my best to consider their feelings as much as I possibly can before proceeding to do things.
