In the old days, when he flew a lot, he'd never been able to get absorbed in a book until the plane had taken off, so he'd spent the pre-boarding time flicking through magazines and browsing in gift shops, and that's what the last couple of decades had felt like: one long flick through a magazine. If he'd known how long he was going to spend in the airport lounge of his own life, he'd have made different travel arrangements, but instead he'd sat there, sighing and fidgeting and, more often than was ever really acceptable, snapping at his traveling companions.
