After years of study, I have known there are only two types of people in this world: those who get to the airport early and those who arrive when the plane is about to take off.

If there were any justice(公正)in this world, early-airport people would be rewarded for doing the right thing. And late-airport people would be punished. But early-airport people get ulcers(溃疡), heart attacks and bite their fingernails to the bone. Late-airport people almost don’t realize they are flying.

A guy of that kind once said, “Don’t hurry. If you miss your flight, it’s because God doesn’t want you to go.” This is clearly a guy who is never going to get an ulcer.

Early-airport people suffer another “name”. They are called exactly what they are -wimps(窝囊废). I know. I was an early-airport person for years. “My baggage will get on the plane first,” I told myself. Indeed it would, which made it the last baggage they took off the plane after landing.

Another strange thing: No matter how early I showed up, I was always told that someone had called two or three years ahead of me and asked for the best seat. I thought it was a trick. I thought there was someone in America who called every airline every day and said: “Is that wimp Simon flying somewhere today? If he is , give me his seat.”

After a lifetime arguing with my wife over whether I really have to pack 24 hours in advance and set the alarm clock four hours ahead, I have learned another fact about early-airport people and late –airport people:

They always marry each other.
