My answer:
You could describe their thoughts and reaction, questions they may have, what are they seeing, what makes the other people different. Here's my thought:
I was suprised, I had never seen a person who looked like these people, they didn't look like me at all. Then a man looked at me and smiled and said something that I couldn't understand, I turned and ran. I had to ask father, who were these people, and what language where they speaking.
Hope this helps, sorry if it doesn't.
