It won’t be a “Happy Halloween” at this Massachusetts elementary school.

School officials at Boyden Elementary School have banned the annual Halloween costume parade claiming the celebration is not inclusive, CBS News reported.

They will instead host a “Black and Orange” spirit day on the holiday at the school in Walpole.

In a letter to parents, the school explained they don’t want to make any students uncomfortable with a Halloween celebration.

“The costume parade is out of our ordinary routine and can be difficult for many students,” the school said. “Also, the parade is not inclusive of all the students and it is our goal each and every day to ensure all student’s individual differences are respected.”

Some parents, however, said they found the decision puzzling.

“That’s the part that especially the parents and the students are having a hard time understanding,” parent Julie Lowre told news station WFXT. “We have numerous events not all inclusive, so if you cancel one event you have to cancel them all.”
