Stereotypes !

Hi,
My name is Rodrigo, I'm 20, I'm from Brazil and I'm here to learn and improve my English before I go to college.
When people think about my country, they're excited about the girls, partys, the carnaval, etc.
On the other hand, talking about negative aspects, they think about the violence, dangerous cities, drugs, etc.
Before coming here to the USA I had some stereotypes in my mind, like, most people have problems with their weight, because there's a lot of fast food here. American people are very nationalistic and I think that they are not hopitable with tourists and visitors.

So, I've been here around 5 months and now I have another idea totally different than I had before I came.
