Dear Jack，

    I'm sorry to hear that you feel lonely in the new school, because you find hard to make friends. Now, I'd like to offer you some advices. Firstly, it's normal of you to feel lonely because you are living in a new environment. Secondly, you should greet your classmates when met them on campus. Thirdly, it would be a good idea if you take an actively part in class activities, what can help them learn more about you. I believe you will be able to make new friends soon unless you're friendly to the others.

    I hope the above suggestions will be helpful to you or everything will be fine with you in the future.

Yours，

Li Hua
