Hmm, profound thoughts...
Once two Tibetan monks were sitting on a hillside meditating. On March 4th one of the monks said, "You know, life is like a streetcar." And they sat and meditated on that for a while.
On April 7th the second monk said, "How is life like a streetcar?" and they sat and meditated on that for a while.
On May 13th the first monk said, "Okay, have it your way. Life is NOT like a streetcar."
