I like your teaching methods, which are straight and repeated explanation with simple illustrations. Give you a thumb up! Also your sub captions have both Chinese and Japanese that give me an opportunity of practicing with Japanese pronunciation and new words. If you can put hiragana beside those kanji in those captions, that would be even better. Anyhow, あなたはとても一生懸命働きます
啊 我以前在英国上学,和日本一样英国也是说话非常含蓄委婉(所谓 high context)的国家,「いいです」和用法 和英国人说的 「it's okay」的用法类似,凭对方语气判断是正面/谢绝(80%)(不过 Its okay大多数是谢绝和原谅吧,正面的话直接就 OK 了 hhhh)。中文的话相比可能就更直接,不过也可以说「这样就好了」不过更类似于「結構です」
