I had plenty of time to reflect on things on the flight back. The plane was two thirds empty, probably an accurate reflection on the current state of tourism in Egypt. I read a National Geographic article speculating that genetics might explain why some people are compelled to seek out distant horizons. I cogitated on my restless genes as the golden light of a beatific sunset suffused the cabin.
A year ago I was also leaving England in a haze of emotion intensified by a hangover. The anticipation of the unknown was replaced this time by weariness and wariness.
