is this answer natural?
5- I would like to talk about a friend of mine who I met in elementary school. Well, we have been friends since then. If I'm not mistaken, he's the same age as me and is the father of two kids. The astonishing thing about him is that he can vividly visualize the things that happened a long time ago. For instance, if I ask him where I sat in the class during elementary school and who was next to me, he will tell my exact location in the classroom. In addition to that, he can memorize a paragraph in a split of second and tell the text without dropping any letters or words. Can you believe that somebody has such ability to imagine things in detail like this!? As far as I remember, he was good at anything concerning with memorizing things. After graduating from high school, he was ranked as one of the top 10 students in the national college entrance exam and now he is a successful lawyer. I personally think a large portion of his success comes from his good memory.
