I forgot to mention one thing about our trip to Mexico. During the flight, I whispered an aside to Sylvia: "I've always hoped that if I were ever in an airplane crash, I'd have the presence of mind and sense of humour to hold my hands over my head and yell 'Wheeee!' as if I were merely riding a rollercoaster."
Ideally the crash would turn out to be minor - one of those where the plane only loses its landing gear and skids to a safe halt with no injuries. I think I'd earn a lot of style points in that case, or a lot of dirty looks from the other passengers.
