I took three years of Spanish and got an A every semester. Even when it was still fresh in my mind, I was nowhere near able to hold even a very simple conversation. And now just a few years later it's all totally gone from my brain.
My mother's native language is Spanish and she never taught me, which I resent her for. But I still find it incredible how shitty my public school education in Spanish was. We really should be teaching kids a second language from kindergarten up.
Haha, it's mostly just knowing baseball well and what commentators are usually saying at any given time and then cross referencing that against my limited vocabulary, but it's fun and useful to be able to parse really rapidly talking native speakers with accents you don't normally hear locally.
(Random aside, but one of the Dominican teams has a deal with a sponsor that sells cranes and industrial vehicles, and every time they make a pitching change, there's a "brought to you by" animation of the crane plucking the old pitcher off the mound and swinging over and dropping him in the dugout that cracks me up every time)
