Etiquette.

There is an unwritten rule in the cannon of church etiquette that grants high school girls the privilege of wearing their prom dress to Church the Sunday after prom. Some girls even try stretching the rule to cover two Sundays. But with that said, this same rule does not apply to Halloween costumes being worn to church. 

This rule especially does not apply when you are thirty. This rule double especially does not applies when that costume is a witch. Just saying, the leggings and eye makeup were distracting. 

FYI, if you're trying to watch the scary movie about prom, you want "Prom Night" not "Prom". While both are highly disturbing, only one was written to be.
