You have hit rock bottom; exposing the phallic proclivities of my dear friend the artist. Lately when friends go to other countries I ask them to bring back a small stone, one that they themselves must have picked up from the ground. So far I have stones from,India, England and Mexico. My most cherished and remembered Christmas gift from my parents, back in 57, was a collection of Rocks and Minerals in a partitioned cord board box, each presented in alphabetical order, with the name and hardness of the specimen printed on a paper label. By the way my artist friend, Chuck, just finished a geology course and he knows the difference between igneous and metamorphic rock, They all look like penises to him.
