Chinese people often say that holding your chopsticks close to the eating tips indicates that you will marry somone from near your home, while holding them close to the blunt ends predicts marriage with someone from far away.

My wife comes from 12 time-zones (half the world) away from my hometown, but when I met her I still held my chopsticks close to the tips. Believe what you choose. I have, however, learned to hold them close to the blunt ends, which I see to be more common among people with good manners.

I have posted a few other comments on chopstick etiquette at Things You Should Never Do With Chopsticks.
