Today students learned words that come in handy when you're learning English. The expression "I know!" and "I understand" came up. Narciso had a ureka moment when he finally realized what people were saying in the kitchen. Up to this point, he thought they were saying "ay! no!" (expression in Spanish). Today he learned that people are saying "I know!" (expression in English).
Everyone had a good laugh about it. Moments like this are the kind that stick - so hopefully everyone will remember what "I know" means.
