Space: the final frontier, but not as we know it here

On a flight to Europe last summer, I was seated between two middle-aged Chinese men. The man in the aisle seat didn't make eye contact, get up or in any way acknowledge my existence, nor did the man in the window seat. They both sat with arms folded, staring straight ahead.

To get to my seat I climbed over the legs of the first one and as I did so, my bag flew out of my hands and landed in the lap of the other guy. I was trying desperately to apologize but neither would so much as glance at me! The flight was off to the worst possible start and I was terribly embarrassed.

Traveling on a bus or train in China, I've experienced a similar personal space puzzle. Most travelers choose the aisle seat and, as the vehicle fills up, will not move to the window seat. Instead, the next person has to climb over the legs of the first passenger who is often oblivious to the problem since there is no eye contact or communication.
