One will often face difficulties when speaking to a nihilist.

A lot of common definitions no longer work for the nihilist and they no longer hold any meaning. Good or bad, better or worse, right or wrong, no longer mean anything to the nihilist. It is a relative world that they live in, having no anchors, definitions or yardsticks for comparison or true objective appraisal of the world we live in.

Yea, once again, I am having problem talking to myself.
