Well it was that night. But here's what I did: I went home, and
   I wrote a note to myself in the future. I set it to the date
   when I turned 42 yrs old. I was a Hitchhiker's Guide to the
   Galaxy fan. I'm 44 now. When I turned 42, after the birthday
   cake and the token presents, I dug through my boxes to find that
   letter. I opened it up. I read it. From me (17) to me (42). I
   discovered that, in _some way_, I managed to accomplish all of
   my dreams so far with more to come and in a sense, I became who
   I dreamed of. I became my own father. For a sad night of doubt,
   something wonderful came out of it: me: and it wasn't long after
   I wrote that letter at 17 that I realized that there's no such
   thing as childhood or adulthood: we're just people.
