*bows to Brancusi*
There's a funny story in John Richardson's biography, A Life of Picasso. Pablo Picasso was notorious for sucking all the energy out of the people he met. His granddaughter Marina claimed that he squeezed people like one of his tubes of oil paints. You'd have a great time hanging out all day with Picasso, and then you'd go home nervous and exhausted, and Picasso would go back to his studio and paint all night, using the energy he'd sucked out of you.
Most people put up with this because they got to hang out with Picasso all day, but not Constantin Brancusi, the Romanian-born sculptor. Brancusi hailed from the Carpathian Mountains, and he knew a vampire when he saw one. He was not going to have his energy or the fruits of his energy juiced by Picasso, so he refused to have anything to do with him.
