That's a fantastic spine-chilling story. It's a classic. I really enjoyed the telling. Hearing the kids' breath, that was a really spooky aspect too.
Another week, another spine chilled! Thanks again for the compliments, Autumnforest. Glad you liked the spooky breath part. This story's first title was The Breathing School, but it was changed after a Google search revealed that there are real breathing schools for people who don't quite have it down yet.
