I think trick-or-treating is a crock of you-know-what.
Kids dress up in costumes that aren’t all that warm to wander around in the cold (and sometimes rain) to get tons of free candy and chocolate, which compromises their immune systems which are already stressed by the lower temperatures. They inevitably succumb to bacterial and viral infections much more easily, resulting in lots of sick children who in turn produce lots of sick adults.
Everybody gets sick, so people start missing important events, like kendo class.
Tonight, we have cancelled kendo class because everyone will be out doing Halloween stuff. I would have rather have been at the dojo. I hate cancelling class. Especially for Halloween.
I look forward to seeing everyone in the dojo on Thursday when I will help you work off your Halloween excesses. Please leave any newly acquired germs at home.
