I took Latin, Spanish and German in High School, which hasn't impacted my life much, other than I'm able to order a beer in most countries (and might be an idiot savant at the Reader Digest vocabulary quiz).
My son Patrick, however, has had some difficulty with his college requirement to take (and pass) four semesters of a foreign language. So far, he's failed German, French and Spanish (twice? This semester's grades haven't been posted yet, but I'm not entirely optimistic).
He's come to the conclusion that he's always thought in German, but never been able to articulate those thoughts (which, some might argue, has been his trouble in English, as well, though he does have a firm grasp of 'redneck').
He's optimistic about the next attempt at German, since he started listening to German music and posting foreign phrases on his Facebook. Today? He ended our conversation with "Ich liebe dich". His accent is sounding gut.
