Tôi có nhiều người bạn thân. Tên của anh ấy là Peter. Tôi biết anh ấy khi chúng tôi còn học trung học. Chúng tôi đã trở nên thân thiết với nhau trong suốt khoảng thời gian ở trường trung học.
I have many close friends. His name is Peter. I knew him when we were in high school. We've become so close to each other during the period of time in high school.
