Yeah, and particularly in the Middle Ages, it had EXTREMELY sexual overtones (Valentine's Day). So...apparently it's not okay for kids to daydream and dress up fancifully but it IS okay to have them participate in a ritual orgy, LOL.Actually, Valentine's Day is really the Feast of Saint Valentine, so...technically that started as a religious day as well. A lot of Catholics celebrate this feast day. The word "holiday" has religious history, as well. It comes from the Old English word "haligdaeg" which means "holy day". We use it in a general sense today as a day to celebrate or in which ordinary activities like work are suspended.
That said: Our school ALWAYS does a H'ween parade! And yes, they call it an H'ween parade. So much fun and even the teachers dress up! Every year they do something awesome. They all went as football players one year, I mean every single teacher, it was hilarious. And last year all the teachers and aides in my son's class went as Despicable Me characters. One year one teacher went as an orchestra conductor and all the rest of the teachers went as members of the orchestra.
The principal did his own thing and wore a giant bizarre circus afro.
