Ok maybe I can tell a short story about me and try to answer your question... I left my parents house at the age of 19( I am now 27) moved to Ireland where I learned English and met people, started working, got my own money and in general became totally Independent! Couple of years later I decide to give my country a try... wanted to live there, because I was sick and tired of being a foreign in another country, it pissed me off that I had to renew visa every three months, had to pay school for a year sometimes just to get that visa that would allow me to stay longer and work "part time" Anyway, When I flew back to Brazil I felt a little nervous, as if I didn't know what was going on... I spent months and months there trying to adjust to new friends, new life again, new economy, back to live with the family and money shortage... but what was constantly in my mind was the fact I missed being abroad so badly, I wanted to return to Ireland where I felt co much more useful than I ever did in my country
It might be because of my background, my parents kept moving cities and I had o move to a different school, so my friendships were all broken in a way... Nowadays I only have like 2 to 3 friends that I keep in touch with over the 19 years I lived there... my life is totally different from theirs... and I feel like I don't fit, so when I am abroad, traveling or in Dublin I feel good. People are doing the same things that I am, like I've learnt to enjoy the same things that they do... I've adapted to the European culture very well and I really like it... I don't know maybe I was never meant to be Brazilian
I can Samba, but I hate the music and the whatever is about it.
But at the same time I wish I wanted to live there and say Brazil is the best country to live like a lot of Brazilians do say when they are traveling... I just can't agree.. maybe that is because I am not rich.... and if you are not rich you go through some difficulties... difficulties that I don't experience when I am in Ireland, with my work I can pay rent, buy clothes eat very well, go out with friend 3 times a week and save a little bit more for traveling to ie. Spain, France.. etc. I have been living abroad of 8 years and I am still not ready to go back.
Well I hope that was what your question meant... This is from a brazilian girl point of view... friends, social life and economic reason and culture. I think it would be a little different with an American Citizen.
