If there was one quality I would want in a travel partner it is the ability to adapt. Stuff happens when traveling. Flights get cancelled, busses break down, things get stolen. The ability to adapt often puts you three steps ahead of the person who sits there fuming.
Adaptability goes beyond unforeseen circumstances, and into you harmonizing with local communities. Understanding the importance of why you shouldn't wear spaghetti straps and a mini skirt in a conservative Muslim community even if its 100 degrees F will save you a lot of stares and unwanted attention.
Communities work differently all over the world. In the U.S. we may be punctual, but in Thailand your 9:30 meeting might start at 11:00. In Europe we invite guests over with wine and beer, but in Ecuador you'll get a “cafecito” or cup of coffee and a finger sandwich if your lucky. Work habits, diet and drinking customs, family dynamics, and daily rituals differ from place to place. Going with the flow rather than gawking at differences may help you see that around the world people aren't so different from one another.
