Counting on one hand, he and I have known each other for fifteen years. We were in the same school and in different classes in junior high school and high school. Although we know each other, we can't be called very close. We just often play ball, eat together, or do other things. Even so, he and I still can't establish a close friendship. Maybe the difference between the two people is really too big, just like people from two worlds, this is true.
