My office used to be in an old house. The attic was where our accounting records were stored and there was a set of stairs in a back bathroom that went up to a "trap door" that had a hinge on one side and you pushed it up to access the attic. There was an anchor with a rope tied to the door so when you opened it above your head, it would stay open.
I was taking a box up the stairs and pushed open the trap door above my head. Just then, the rope BROKE and the door came down on me and the anchor crashed into the floor. Luckily, my hand was on the door over my head and i was able to keep it from hitting me and only went down one or two steps, with the box of files in my hands.
Our new admin assistant never got up from her desk to check to see what the noise was! I walked into her office and said, "hey, did you just hear that big bang?" She says, "yeah, I heard it." I then said, "well, next time you hear that kind of noise, you really should go see where it came from" and proceeded to explain that I could have been hurt or dead.
Some people are oblivious!!!
