I first started learning a second language in about 6th grade. Well, formally speaking anyway. Having been raised in as ethnically diverse a neighborhood as my hometown, I was exposed to a multitude of languages. The most prominent of them were French, Jamaican patois and Haitian Creole. My French isn't polished, but I can write Haitian Creole fairly well. I used to speak Spanish with semi-fluency, but it's been so long that I've gotten supremely rusty. I was formally taught Spanish in elementary school, which is probably part of why it didn't stick. Book learning and real world learning are completely different.
