Secondly, regarding how to open a topic or choose a topic, not only can communication be established by greeting or asking questions, but also "sports" and "movies" are topics applicable to anyone in the world, especially in Canada, where people are keen on outdoor sports and other sports activities because of its high-quality natural resources.
