topic: choose three members of your family and write facts or speculations about each one.

I know a lot about the members in my family, however, there are many things that I don’t know and I have some speculations about them.

The first person is my mother. She was born in 1977 and an interesting fact is that she has a twin brother. I think it was extremely difficult to distinguish her and my uncle at that time. But when they grew up, the simillarities between them significantly reduced. And at present, if someone who is not a member of my family sees them, I'm sure that he will not believe they are fraternal twins.

The second person is my great grandmother. The age of her is over 90 years old now. And certainly, she lived in war time of our country. According to the stories she told me, it’s possible that she bravely fought at that time.

The last person is my father. In my mind, my father is accomplished in many things. He is both a teacher and a farmer. And he does those things very well. My father also teaches that I have to hard-working and try to do many things I like in the best ways. I think that he faced a lot of difficulties and tried to work very hard to become better and better.
