Trick-or-treating began with roots in the ancient Celtic festival of Samhain and the medieval practice of "souling," brought to North America by Irish and Scottish immigrants in the 1800s. Now Trick-or-treating is a fun yearly tradition popular with kids and adults alike. Most people like to give candy to kids but some people enjoy a little trick like giving out fruit or even a toothbrush. So, are you the one who rewards the children with sugary temptation? Or do you enjoy their looks of surprise and shock when you drop a healthier alternative in their bags?
