After sleeping a jetlag away it is a time to go through paper piles, business cards, flyers, catalogs and booklets. Distance faded out the faces and you are instinctively ranking the paper piles in order. Couple of them are burning in your hands and you are going to email amazing exchange ideas to those people… but is better to stop to think in your own language for a moment to get your thoughts in order. Exchange is fun, but just a empty shell. A mark in CV does not feel worth of bothering if there is no content or other purposes than travelling. Non-commercial art fairs are also more or less just travelling. But without them business cards are nothing more than a pieces of paper, so there is a point to gather together. To attach faces on the papers.
