Turning Brown
A four-year-old boy was eating an apple in the back seat of the car, when he asked, “Daddy, why is my apple turning brown?” “Because,” his dad explained, “after you ate the skin off, the meat of the apple came into contact with the air, which caused it to oxidize, thus changing the molecular structure and turning it into a different color.” There was a long silence. Then the son asked softly, “Daddy, are you talking to me?”

I read a study that measured the efficiency of I locomotion for various species on the planet. The condor used the least energy to move a kilometer. Humans came in with a rather unimpressive showing about a third of the way down the list ... That didn't look so good, but then someone at Scientific American had the insight to test the efficiency of locomotion for a man on a bicycle. And a man on a bicycle blew the condor away. That's what a computer is to me: the computer is the most remarkable tool that we've ever come up with. It's the equivalent of a bicycle for our minds.

Languages and cultures use non-verbal communication which conveys meaning. Although many gestures are similar in Thai and English such as nodding for affirmation many others are not shared. A good example of this is the ubiquitous “Thai smile”. The “smile” carries a far wider range of meanings in Thai than it does in English culture. This can sometimes lead to serious communication breakdowns between Thais and English speakers.

An example from my own early experience in Thailand illustrates the point. When confronting the Thai owner of a language school with administrative problems, complaints regarding student numbers in the class were met by a beaming smile and little else. I took this to mean lack of concern or an attempt to trivialise or ignore the problem. I left the discussion upset and angry by what appeared to be the owner's offhand attitude to my problems.

It was only later when another native speaking English teacher, with considerably more experience of Thailand, explained that a smile meant an apology and the fact that the following day all my complaints had been addressed, that I fully understood the situation.
