I am glad to receive your letter.from your letter,I know you are facing the problem on making friends in your new school. But I think there is no need to be worried. Since the students in your class come from different places, they may have the same trouble with you.So you'd better join in their games in your free time and have lunch togehter.In a word, as long as you get in touch with them actively,you are sure to make friends with them.I hope you can have a good time in your new schol.
Look forward to hearing from you.
