As children, we put on costumes to get some candy. Sometimes, the parents put a lot of imagination into what is worn. And they parade us around to show it off.
When we grow up, it is the houses that are decorated for all to see. Costumes are worn at parties to celebrate the season. It is a good time to put your cares aside.
Scary movies will be watched one after another. We can enjoy fake violence with no remorse. It is a break from the real kind we see plastered all over the news.
Imaginations run wild with the deep dark possibilities. As long as no one gets hurt, a fun time is had by all. Just pure exhilaration until the final bell tolls.
Afterwards, we have memories to look fondly upon. Those who become desensitized were not very sensitive to begin with. And then we wait for another year to pass.
