Why are people so afraid of saying that phrase? I have noticed it at work, with my family, with random strangers, it is like they are terrified that people will think they are stupid, or that there pride will be hurt if they admit they do not know something. It is one thing that I have never had a problem with; the way I see it, if you just make some stuff up or try and change the subject, you are just being like a child. I have literally no issue with telling someone that I do not know something if they ask and I do not know..should I be?
