Onebyone, I like your style! I think for some (me too!), it's a matter of pride. I'm pointing out the mistake as if to say, "I know it's there already." Like beating someone to it... It takes a lot of guts for most people to accept a critique. I personally want to know how I can improve. Some people can point out a mistake and it grates on you, whereas another is so gracious and helps you figure out how to fix it that it doesn't feel like criticism at all. Wish we could all learn to be gracious and helpful and willing to accept help.
