192 trick or treaters of the proper ages (babies- seventeenish).........about 20 trick or treaters of improper ages (18-come on, really?) Trying to pull a fast one for that sweet, sweet candy without a younger sibling or child of there own and most likely very lame costumes in anything at all............I'm gonna say 33 trick or treaters that do have their own children and present with them (ages are irrelevant, however these parents are most likely not wearing costume) but as well as the rest, they too want that sweet sweet candy.............20 trick or treaters will come to your door in hopes that you won't recognize them by lack of memory, but when they find out you're a poker player they'll start to interchange costumes accessories and becoming really weird characters (this works and that 192 just grew +20) ..............your street must be pretty popular for this occasion and I don't know if you are a dull type of person but my guess says you're not, so I'm pretty sure you are having some guest's over tonight and 100% of them are going to knock on the door saying.."TRICK OR TREAT"(you will a Blige by giving them candy, thus making them included in your count) I will guess a full tables worth , with spouses and children so roughly 20 guests. .............because it is Monday though I'm going to cut the total in half sooooooooooooo.............151 - 305 without the split............no split....305 final answer
