I minored in Spanish at a school in the Southwest, and now I'm stuck in the Midwest for med school. In any major city here, there are LOTS of people who speak Spanish. This means I got lots of Spanish speaking patients dumped on me during OB/gyn and Family Med. It helped when I didn't have to call a translator or use a blue translator phone at 5:40 in the morning during rounds, and I translated for a bunch of my friends.
Before med school, I hadn't spoken it for 6 years, but it came back well enough. I just don't tell many people in clinics that I speak Spanish, unless there's a translator crisis and we're way behind, since I don't like speaking it; that's then how I get all the Spanish speaking patients dumped on me.
