Taipei Update

So much to say, so little time to write. It’s sad, but you have to arrive 2 hours before any international flight, plus, in my city to get in the airport secure, you need at least 2 hours, this sums 4 hours, plus 10 hours of flight to Amsterdam, then 8 hours to stretch a little bit, little walk in red light street, eat something, shower and 10 more hours to Bankgok, 1 more hour waiting, then the final 3 hours to Taipei, and when you arrive you are 12 hours ahead… Computex already started and it’s a boom, I…
