I’m a world traveler, right? A “jet-setter,” some say. No arrogance here — just a fact. So how did I make such a cultural goof?

Here’s a typical work week: New York City, Connecticut for a family visit, Kansas, home for 24 hours, then off to Dubai. That was an actual week in January.

Other weeks might include Italy, Singapore, Australia, Peru, England… and I pride myself on having some awareness of basic cultural expectations. I bring gifts to Japan, dine late in Spain, offer and accept things with two hands all over Asia, eat with my right in India, and understand that “just now,” in South Africa, means later. As in, “I’ll call you just now.”

In Connecticut, I burned my right hand when the lid fell off my sister’s faulty tea kettle. Okay, there’s nothing wrong with the tea kettle. I just didn’t put the lid on tightly. Next day at a meeting in NYC, I nearly fell to my knees when a handshake reminded me of the scorch. There were lots of handshakes that day, and I quickly got into the habit of using an upside down left with “sorry, burned my hand.” This continued as blisters popped in Kansas.

By the time we got to Dubai, soft scabs were forming and my lefty handshake was second nature. I realized the gaffe in the midst of committing it in that muslim nation. Meeting the owner of one of Dubai’s spectacular hotels, he was gracious while I was a blubbering, blundering idiot with a mouthful of apologies.
