Who benefits the most at an international school?

I`ve realized that I don`t give my job nearly half of the credit it deserves.
Since September, I´ve been at an international school, which is quite a change for me, coming from my experience working for the US Government. I absolutely loved working at my old high school, and am so thankful for my 5 years working on a military base. The people I met were all wonderful, and my base access provided me with a much needed link to home that helped me transition into living abroad.
Now that I feel I have sprouted some roots here, I feel like my new job is really a perfect fit for me. I adore the international community. While I am not entirely with Germans, the international school provides me with the opportunity to meet people from all corners of the world. And while I will probably never get to live in many other countries (after all, I am fortunate to have two home countries now,) I am simply so delighted with the experience of working with kids from many other countries.
My lesson today? Colors.
The Japanese kids have been drilling me about colors for months now. But today, as I sat with a Japanese girl, an Italian girl, and a German boy, we all discussed colors in our native languages. The experience was incredible. I feel like I don`t deserve pay for a job that provides me with daily opportunities to learn about the world around me.
So, here`s what we talked about today:
ENGLISH JAPANESE ITALIAN GERMAN
blue ao blu blau
red aka rosso rot
yellow kiiro giallo gelb
white shiro bianco weiss
black kuro nero schwartz
purple murasaki porpora lila
orange oranji arancione orange
green midori verde grun

Okay, so it looks like a boring vocabulary list, but put into action, and conversation between a 28 year old, a 7 year old, a 4 year old, and a 3 year old, the experience was absolutely incredible. I am so lucky to be a part of this world. So my question: Parents spend thousands of Euro each year to send their children to our prestigious school. But in the end, do the kids or the teachers benefit more from this very unique and wonderful community?
