Ok so... you, as a house hold, buy candy...you then answer the door the neighboors who beg for the candy in their own little childish way "Trick or Treat" and you give away candy you paid your money for, THEN you go around and do the same, so you are kinda just trading candy for candy you buy it loose it and gain it again... personally being the sugar freak i am would just buy shit loads of candy (saying i am buying it for halloween) and eat it all myself...seems more logical anywho I LOVE CHER!!! well not love just asome songs...*sigh*...
