If you were looking forward to a quiet flight, but your loquacious seatmate has other plans for your journey, what do you do? You can't choose your environment, so create your own. Make sure you have an eye mask, earplugs, earbuds, or reading material on hand. Then, smile at the chatterbox beside you and politely tell them that while it was nice talking, you're now going to try to catch up on your reading. Or sleeping. Or watching the in-flight movie.
