Oh, I'm not worried! There's probably just a temporal fold somewhere nearby, or, failing that, I could call my friend up, because he owns a time machine! Or, right, I could call me now and ask me how I got back then in order to become the me that's now, although that would be an ontological paradox, which might be bad! Hmm! You know, growing up near temporal rifts is a major source of psychic phenomena, apparently!
