Halloween

So this year has really brought a point out that that has been bothering me for a few years. Remember when we were kids and Halloween was celebrated on Halloween? Yeah that doesn't happen any more, one town has it on Wednesday, another on Thursday, and some on Friday night. Is this so that our children can get 3x the candy? Or is it so I can cherry pick all of the good stuff from Carter's stash? Another thing that I don't remember is when did it become the norm to dress as slutty as possible for a costume? While I do not nor will I complain about this phenomenon, I just want to know when the switch was made from young girls dressing as cats and Dorothy to dressing as slutty cats and slutty Dorothy? It makes me very glad that I have a boy and not a girl.
