I don't have any; I just live my life one step at a time, but perhaps a bigger step than normal people would.
Some of the nursery rhymes I don't recall, or might even be the case that I've never encountered them. Some of the fairy tales I don't remember the ending, or perhaps even the climax. Songs you sing in your youth, I've never heard of; cartoons growing up with you, I've probably only heard of the names at best...

While people are still believing in their happily-ever-after, I've began thinking how and when I'll die; wondering if there is another exact same me existing in the same universe; pondering if I was the protagonist in a sadistic reality game and everyone else around the supporting actors.
Perfect childhood, I don't have; but I dare say it was an awesome one...
