It's scary when there are people you can have full conversations with, without saying more than two words. One of the people I have this with, is my brother Tjerk. Yesterday we were watching Space on the BBC and there was talk on Biosphere. He said "Just like...", I glanced over, said "Yeah" and we both laughed. Each of us knew exactly that we were talking about the lame movie Bio-Dome, starring Stephen Baldwin, we had seen about a year ago.
