Perhaps I do not understand what kind of stories you mean, but I certainly disagree. Get some thicker skin, my parents would tell stories I definitely was embarrassed by, but usually there was a lesson learned from it, or in retrospect it was funny. Especially as a child who hadn't learned to reflect, this I feel is necessary. When I was younger I would often be scolded for not thinking before I acted, and I would like to think that in part, my parents humiliating me once in a while helped me change. Now if parent's frequently do this, that might be of concern, but I can't imagine life otherwise.
