Conversation Strategies: Natural versus unnatural questions

This is a video from Action Language Academy, an Eikaiwa (English conversation school) in Japan. The video is called, 英会話 名古屋 Typical English Mistakes-1: Hobby. The video talks about a common mistake students in Japan make during an English conversation. The mistake that they make is asking the question "What is your hobby?" They make this mistake because the Japanese word 趣味 (shumi) is translated as "hobby". However, "shumi" can be translated as interest or favourite pastime.
