I see. I guess I am an example in favor of your theory. I'm not entirely sure that this is an unambiguously good thing, though, because sometimes you should impress your peers in ways adults would not approve. Or, to put it another way, the optimal balance of grown-up-ness and fun shouldn't have a factor of 0 for either category...
(I suppose if the adults were never wrong about classifying things as fun-but-harmful, then I'd change my mind.)
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
