Dear Peter,
As you known,I want a English pen pal.So I need your help.
Fisrt,I hope my pen pal is a kind person ,we can help each other in the future.Then,if he or she has the same hobby as me,such as football and basketball,it can't be better.By the way,boy and girl both can be my pen pal,but he or she can't be too old,I want a student
to be my pen pal.
If you can find a people like this,I think we will have lots of thing
to talk about with.Happy things will be around us all the time.
Finally,thank for helping me.
Yours,
LiHua
