And, no, you did NOT have time to grab your bookbag, or the book next to your bed. You were . . . grocery shopping when you got the call and have nothing with you but your wallet and your passport (which you fortuitously brought with you in case they asked for ID in the ethnic food aisle). This is hypothetical, remember….
Well! My very first reaction would be "WTF? Where did this cell phone come from, and how did my family know to call me on it???"
But since we are being hypothetical, once I got to the airport, I would go to an airport bookstore to see if they had books with detailed analyses of the current state of the world economy, and at a minimum, buy a copy of The Wall Street Journal and/or The Financial Times.
Now ... in reality, I would get home from the grocery store, and The Tim would either tell me about the call, or it would be on our voicemail. (Yes, we do have voicemail. Because we are all about the modern.) If this were the type of emergency that required The Tim's presence as well, I would need to find someone to come and feed the cats while we were gone before I left for the airport.
So, saying that had been taken care of easily, and I left the house for the airport otherwise in a hurry, I would check out the airport bookstore once I got through security and had promised ownership of my house to TSA in the event they found a killer pen on me or a shoe bomb. If my flight was actually "on time" (hypothetically of course), I would likely buy a shallow magazine to pass the time in the airport and on the plane.
If the flight had been delayed, or cancelled and I had to wait to be rebooked somehow, I would probably still buy the magazine, but also a book, though nothing too serious, and definitely paperback. I would take turns looking at the magazine, reading the book, and people-watching. I find that the airport is an excellent place to devise entire life stories for people. You generally have time to give them names, back stories, and a great story of how/why they are at the airport. (Like for instance, they were at the grocery store, and they got a call about a family emergency ... oh wait, that's what I'm supposed to be doing ...)
