The differences between us

Being a military kid, I have been in many different cultures and with many differ races as well. And it's amazing how many differences there really are. Out of all of those, at lest from my experience, clustering causes the least emount of trouble.  Language differences a probably the most demanding in a work place. Like when your up north, coke/soda is called pop, in Aulstriala  a rubber is an eraser... That one was really awkward. In Hong Kong chips was either alive or fried centipedes in baggies to eat-shutters-.
Next I think the tone of voice is probably the next most important. Americans have very monotone/flat voices compared to most cultures, when I was in Germany they all thought had depression issues, until I fixed the fluidness in my voice. And there can be so many misunderstandings if you say small things with the different tones of voices. Because the tone of voice is pretty much like body language, you don't have to know the language but the tone of voice can tell you, if there is danger or is the person is pissed off... You don't have to be genius to figure the basics out.
I would put the values in third place, because if the people your communicating with know your not from around there, and you mess up and apologises they typically, exsplane their values and if you seem interested in learning more about them, they tend to become excited to share more. So as long as you can listen and at lest seem interested, they tend to think your pretty cool and are more likely to forgive.
A for the clustering, as long as your pretty willing to learn to go with the flow, it's not hard to be excepted.now again, they is probably because I have lived in about 10 different states and been to 5 different countries and lived in 4 different countries(I don't count living in a place if I was there for less than 3 months) the first time I moved I was 2 years old, then after that on average I moved every 6 months to 9 months. So the clustering my never have effected me as much because I never grew up with the one group and the same friends. I've been forced to learn how to live  and make friends with tons of different friends. So at lest for me, it isn't a big deal.
