Learning Language Is Difficult...

Alice, my friend, just sent me a joke (see below) and I'd like to share it with you and see if you will smile on it. In fact, one of my friends happened to the situation before. The story goes like this:

My friend did not know how to speak Taiwanese, but he was going to see his girlfriend's mother, who came from a Taiwanese family. So, we tried hard to teach him at least one sentence: "Auntie, how are you?" (In Taiwanese: 阿Mm, 你吼?)
However, when he met his girlfriend's mother, he said, "Mother, how are you?" (In Taiwanese: 阿母, 你吼?) Since then, he has had a nickname: 阿母!
