I had noticed one danger of Halloween is what happens when kids eat all of that sugar! Mine start bouncing off the walls, running, yelling and causing havoc in the house. They break furniture, fight, throw stuff, and act like uncontrollable imps. Then the sugar crash comes on and all hell breaks loose. God forbid a parent request they pick up all those candy wrappers, an all out fight in itself. Good luck protecting them from imaginary tree jumpers, protecting them from themselves is job one!
BTW, when did Halloween become an officially recognized holiday?
