What is the truth? It is still a puzzle to me. Arthur Schopenhauer said that every truth passes through three stages before it is recognized.  In the first, it is ridiculed, in the second it is opposed, in the third it is regarded as self-evident. 

What she has done, she will do again;
She will bite her tongue, careful or not,
Upon the already-bitten spot.
Maybe there is no truth.  There is only perception.
