Even more confusing, yo soy yanqui learning Spanish in Argentina. I can't tell my tu from my Ud. from my vos. Everybody looks at me very funny when I use sos en lugar de eres. I get some funny looks from Mexicans. LA C****A DE SU MADRE!
Also, why don't the know nothings understand that countries below Mexico are not filled with guys wearing sombreros and ponchos while riding burros?
