The flight from Heathrow to Boryspil should have been an indication of what to expect. I shared it with a group of Ukrainian students returning from a school-trip. iPads, beats headphones and the latest trainers made me assume that these were the offspring of Ukraine’s ruling class. They behaved just like any teenager in the “West”: in equal part plainly enjoying themselves and making their best effort not to show it too much. At sixteen, being happy isn’t cool. You’re supposed to have outgrown infantile bliss.
