I always grin at this one because I know I fit right in with the missing third group. We're still looking for that some number to be X.
Well, this quote was much more sobering.
I believe that the enemy divides all people into two categories: those he can ignore, and those he has to fight. I want to be one of those he has to fight. (R. Logan & T. Clegg)
No joking here. Have you thought about where you fit in? In this case there isn't a third group option.
