The mind that becomes soiled in youth can never again be washed clean; I know this by my own experience, and to this day I cherish an unappeasable bitterness against the unfaithful guardians of my young life, who not only permitted but compelled me to read an unexpurgated Bible through before I was 15 years old. None can do that and ever draw a clean sweet breath again this side of the grave. Ask that young lady—she will tell you so.
