Leaving on a graduation school-trip in Crete

It's a tradition in my son's college to go on a graduation holiday before the beginning of the last school year (college here is 4 years, and my son will graduate early next Summer). So this morning off he went on a plane to Crete with over 100 of his fellow school companions. He was looking forward to the trip, already wearing his "holiday sunglasses", as his father drove him to the airport.
