Being white south american in europe is quite strange, people (usually old people) ask you were you are from assuming you are going to say germany/france/italy/spain and when you say a country in SA they first frown, then, in their heads, they try to reconcile their views of that country with their views on your skin color.

For example I got told several times I don't look Brazilian and one time I remember someone completely changing their attitude (for the worse) after mentioning I was brazilian

I have one last name or German origin and one of Portuguese origin, I started putting only the german one in CVs
