We do make a difference

If ever you wonder why you came to China, consider this.

We do make a difference. I received an email about half an hour ago from a student I taught last year in Junior 1 (Grade 7, 12 years old). This was it (completely unamended, exactly as the student wrote it)

Dear Bob,
Hello!How are you?
I am a student in the No.11 middle school of Baiyin City in China.I am in Grade8 Class 1 now. Have you remembered?
We have not your class this year. And we have seen neither you nor Megan since this term began.Where did you go?Have you gone to another country? Or just have gone to another city in China? Will you come back？
Thanks a lot for returning every e-mail from me.Do so many students write to you?
Best wishes for you.And looking forwards your e-mail.
Miss you very much.
Yours sincerely,

I replied briefly and a few minutes ago received this one from the same student.

Dear Bob,
You always reply so quickly.I'm very glad to know that both you and Megan are still in China.And I'm surprised that you are still in Baiyin,too.
Our lessens are good.And we are still working hard.But without you and Megan, everybody is a little unhappy.
I'll tell my friend your e-mail.They will write to you.I'm sure.
Thank you again for your replying.It's deep night,so you needn't to reply.
Good night.

I really wish that I thought anyone in my current Senior 2 class (Grade 11, age 16) could produce work that good.
