When DD was 7, she dressed as Frodo, and recited the entire "one ring to rule them all" poem at every house. Much to the amusement or bewilderment of the adults each time.
I wish that your DD had visited my house for Trick or Treating at 7. It sounds so cool.
On a related note, DS8 dressed as a Red Ninja and recited the witches chant from MacBeth at every house this year with dramatics, sound effects and cackles - much to the confusion and bewilderment of everyone. But, he was told that he might end up as an actor in his later life!
