===== From t.degroot@inter.nl.net: I am not sure I get the idea of "absence" here. On the contrary, this is strongly evoquing "presence"! The point is that the bombs not having exploded is not a feature of absence in itself. They are just there, waiting to be used. They do not miss anything. ===== From jminner@sc.rr.com: The concept is original, but the depth isn't too great.
