The hugs were out of control at West Sylvan Middle School.
Students could not pass each other in the hallway without a hug, the principal said. The girls were hugging one another all the time. Kids were late to class because of the hugs.
Classes would end, middle schoolers would eye a classmate at the other end of the hallway, "they'd scream, run down the hallway and jump in each other's arms," Principal Allison Couch said.
It was, Couch said, a virus of hugs.
So the principal banned hugs on the school campus in late February.
