As a former child, I'm not sure I would have wanted the adults mimicking my behavior. Back then I loved the occasions where the adults and us kids got together, such as festivities, and I got to hear their stories. They were all interesting and serious people though, with interesting lives and jobs (I was born in the 1970s and many of the adults had experienced WWII, or, the parents, the hard years following it - I am [East] German). No strange opinions about science or politics.

I think that's similar to when politicians try to "be like the people". I think "normal people", and children, prefer that their "betters" are actually examples of something better.
