“Should you go on, you will surely be disappointed, perhaps even heartbroken. I have one key left on my belt, but all it opens is that final door, the one marked. What's behind it won't improve your love-life, grow hair on your bald spot, or add five years to your natural span (not even five minutes). There is no such thing as a happy ending. I never met a single one to equal "Once upon a time."
Endings are heartless.
Ending is just another word for goodbye.”
