Some people just can't take it though. I've seen it in everyday life as well as here. At work recently, a 50 year old professional was spoken to about this or that, and it turned into a fiasco. Instead of "Okay, I'll take care of it, or I'll stop doing it that way,", he had a meltdown. It's never anything but a personal attack, and there is always some excuse, or they are being singled out.
No matter what it's the risk we will HAVE to take here or anywhere. You can't be so afraid of offending that you stop even trying to help. As long as you offer the criticism in a polite supportive manner, even if they do blow a gasket, no one can fault you for trying. This very thing happened to me recently in a thread from a newer member.
