Talking with a nun

We often visit nuns after school,and talk an hour everytime.There are two students per a nun.When I visited nuns for the first time, I couldn't hear what she said because she is above the age of eighty.Her voice was difficult for me to hear.I felt down about my listening skill.But,I was motivated soon, so I could hear and talk a lot to her next time.We talked about many things such as our dream, hometown, family, and so on.I showed her some picutures of my hometown and shrine on New Year's Day, and explained about them.It was difficult for me to explain Japanese tradition or custom, but I think that to exchange each culture is benefit for each other.I like to learn other country's culture.Then, she asked us what the most difficult thing to study English is.I told her about my story in a store. When I went shopping, I wanted to buy a "brush", so I asked a clerk where the brush is. But, she led me an area of "blush". Also,I asked a clerk whether there are some water, but he didn't understand what I said at first.My teacher or RA understands my pronunciation,but it is hard for people who don't get used to English spoken by Japanese to understand my English. After I told the story, she suggested to us we practice pronunciation, so she taught us correct pronunciation, and difference of "R" and "L". As I'm poor at pronouncing "R", I practiced hard with her. I probably got well. Then, I heard what she used to do as her job. She helped poor people and black people, and taught English literature to them or other children. And, she opened a store that sold clothes and sundry goods. She has done everything with charity. She has never gotten married, and lives for other people. I think she is estimable people. I can learn lots of valuable things by the nun,so I'm always looking forward to seeing her.
