The Thoughtful Warden
作者：管理员THE Warden of a Penitentiary was one day putting locks on the doors of all the cells when a mechanic said to him:
"Those locks can all be opened from the inside - you are very imprudent."
The Warden did not look up from his work, but said:
"If that is called imprudence, I wonder what would be called a thoughtful provision against the vicissitudes of fortune."
