He was kind.
I couldn't understand all of conversations with him, and yet he talked to me naturally. That was normal like a talk with native speakers.
I was glad and chagrined.
I think that he didn't talk to me as a Japanese, he talked to me as a friend.
Therefore, I wanted to know what he was talking about.
And I wanted to make conversation like a friend.
So, I have been learning English since then.
I like persimmons.
