My problems started after I went to a boarding(寄宿) school.I was only 14,and at first I missed my family a lot.I often called them and cried on the phone.But after two weeks,I found I enjoyed being with my classmates at school. I had many friends who were boys.I thought of them as my best friends-but only friends.I never guessed my friendships with boys would become a problem.

Then,three months later,my friends told me that some teachers and girls said I was hanging out with boys all day long in order to get attention from them.Seven months after that,the head teacher Mr.Wang asked the class to choose some students to join the Student Union(学生会).I thought I could win for I was doing well in school.I’d already won prizes for the best math and English exams.A week later,the list came out and it didn’t include me.I was sad.

Mr.Wang came to me and said,“Don’t be sad.I know you’re excellent! Maybe you are a little distant(疏远的)from the girls in our class.They don’t know much about you,so some of them didn’t choose you.It doesn’t matter.Do your best to get along well with everyone and I think you’ll make it next time.”
