Hey Piamed, thats typical, dont worry, when I arrive, the kids say, he is big and so white, (i.e. Kano) and they all call me Joe.
You will be a novelty for them, sometimes they are not being rude, I am sure you dont feel they are, your probably fit and slim big, whereas with me, I am not fit and certainly not slim, so for them I am huge...
I laugh it off, glad to hear you are having a great time.
