A vibrant, creative child who is frequently scolded for being "too much" embraces her bold side in celebration. On one hand, it was refreshing to see a girl in particular being welcomed to express herself and stand out from the crowd.
On the other, there are times when "inside voices" are appropriate--it is made clear that she lives in an apartment in which sounds travel through walls, and intruding on another's need to sleep, study, or work isn't okay, either. (Been there, done that.) Perhaps her parents should see this as an opportunity to take her to the playground or other noisy places in which the decibel levels won't be an issue.
