We (had) a door with a large glass in the middle. One day the wind caught hold of it and slammed it shut taking the whole section of glass and spraying it down our 8 foot hallway. This was not safety glass. So very large knife-like pieces went charging down the hallway. We were grateful and blessed, that we where not in the hallway when this happened. I don't want to even think about that one. The Elders were there too, and they pitched in to clean up the jagged works.
