Okay, so my good ol' chum just brought up this argument we've been having for about eight years now.
It started when I was so mad at him I said I would build a time machine, travel forward in time and kill his children*, then travel back in time, killing him.
He posits that by doing the latter I couldn't have possibly committed the former. However, since time-lines are relative, I believe in my body act out these events in that sequential order before permanently changing the timeline.
WHAT DO YOU THINK HALFORUM????.
