Dear Mary,
How are you going now?
I would like to tell you something about my school life. I'm feeling upset these days. I think my classmates are not friendly to me. Last Saturday, one of my classmates held a birthday party. He invited many of our classmates ,but he didn't invite me.
How can I get on well with my classmates ? I'm sure you can help me. Can you give me some advice ?
Betty.
不知道有没有格式的要求,参考下.希望能帮到你.
所以烦恼究竟是什麼。。。能给点具体信息么
