Ahhhh I am just like the disgruntled person in that thread. Nodes and displacement and all that is above me. And I still don't like toes, belly buttons and nipples showing even though they are painted over. It's too much like those Sports Illustrated models and their body paint. Technically, they are still nude.

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
