Once I tried to explain something about pregnancy control to Lin, it was difficult because I wanted to talk about a specific situation, and I didn’t find the specific word. In another situation you can reformulate the phrase in order to express the same but with different words. So for these kind of conversational situation you must know the vocabulary if you want to be understood. I don’t think it was humorous instead of that it was to frustrating, because It is something do in daily work in Colombia and in that time my attempt was unsuccessful.
