What is this holiday?

So... does any one else ever think about is strange holiday that we celebrate, year after year? I was thinking about it and I think it is so humorous. Here we are good parents and mothers, monitoring our children's health and well being but one day a year we drive them around to other people's house and encourage them to fill up an entire bag of candy to devour in pretty much one day!!! Does that seem odd to any else!? Then the best is the famous "TRUNK OR TREAT"! Thisway we can fill up an entire bag of candy in half the time and then still have time to go to other people's house to get more. And the funny thing is that I actually catch myself getting competitive. "Hurry! Just go to this house and then run over to this house and I will meet you over there. RUN!! There are more kids coming!" Then after this exhausting excersise, we come home and dump out our (notice I am included) candy to find 5 full bags of candy that I would never let my kids buy!! What are we thinking?! O'well, I guess I will start my no sugar diet after Halloween..I mean Thanksgiving.. Christmas??!!
