Call me old fashioned, but if you are taking your toddler out Tricks and Treating in his/her wagon, please refrain from using the cup holder in said wagon for your Labatt Blue. And if you have to carry that child to the door because they aren't steady on their feet, please put your cigarette out before you pick them up.
Also, I know your dog can't eat chocolate. So don't be dressing them up as a Hot Dog or a Ballerina and carying a bag for them.
Finally, if you are 14, and want to dress as a nerd, the glasses with tape are a perfect touch. The skirt that sits 7 inches above your knees (and about 5 inches below your you know what), is not.
