Who can say they’ve perfected their skill in a language? Have I perfected my ability in English? I mean, I was born into an English-speaking culture, and I learned that language first, and it was the only language I understood until I was in my teens (if knowing what ¿cómo estás? means can be considered understanding Spanish). Even today, there are English words I don’t know; on top of that, there are English dialects I don’t understand very well, accents that I can’t compute without some thought. Can anyone ever truly complete their study of a language? And if not of your first, how much less of your second, third, and so on! But this shouldn’t discourage us in the least; in fact, it should be an energizing revelation.
