While having a writing workshop with my class of seniors we heard a loud crash. It sounded like someone had push a case of books down the stairs. Of course, we went to investigate and discovered that next door in the girls bathroom part of the ceiling had collasped. One of the metal fan was hanging by its wires. Thankfully there were some Japanese teachers that came running as well and were able to report it to the appropriate people. For the rest of class students would look up ever so often to make sure the ceiling wasn't going to fall on them;)
