1. The Spanish you learned in high school is nothing like the language spoken here.
The first time I heard two Spanish brothers call each other “tío“, I thought, “hmmm… that’s odd. Why would brothers call each other uncle?” The Latin Spanish taught in American schools and from highly-acclaimed language teachers like Professor Dora the Explorer, is just a tad bit different than the colloquial language in Spain. I like to think of it as the subtle differences between American English and British English. Lift, meet elevator.
