His classmates have elected him as class monitor because they know Peter is reliable. He has devoted a lot of time to helping his classmates and the class teacher, earning him high praise. Although he is very busy, he manages to do other activities such as guitar lessons. His parents were concerned that guitar lessons would take up too much of his time, but Peter assured them he made such a strict schedule that he could handle it.

If his friends have a disagreement, they often approach him because they know he will speak the truth and give his honest opinion.
