Lacking passion in tutoring

When I am having a English free conversation class, some of tutors aren’t interested in talking with me.
Then I loose my motivation.

However ,I ask something to break awkward silence such as “How long have you been in America?”.
If the lesson go like that, it’s pretty tough time for me.

生徒に無関心な講師

オンライン英会話で、フリートークをしていると、困った事に時々こちらの話に全然興味を持ってくれない講師に当たる事があります。
そんな講師には、私の方も特に興味を持つ事がありません。
しかし、場を持たせるために、「How long have you been in America?」等の適当な質問をする事があります。
そうなってしまうレッスンは、結構きつい。
