I grew up in San Diego so when it came time to choose a language for high school, I picked Spanish. I took it for all four years, plus one more semester in college. It has been useful, even a little here in Virginia. At my peak, after high school, I described my fluency as that of a preschool child (plus I could write short essays!) but now the thing I say the most is "Hablo pocito español" and single words like pointing out the color "verde" to a kindergartener.
I think it's awful that we don't learn second and third languages from young childhood in school here in the U.S. and admire people who are multilingual.
