Dear penpal,
thanks for you last letter! i'm sorry i haven't written so long,but i haven't got any free time.
well,in your letter you told me about christmas in england. it is very interesting,i think. thank you so much for the invitation, I really appreciate it,but I’m afraid I’m not able to come,I’ve got too much on at the moment. but i hope,that i will celebrate this holiday with you next year.
So, i have to go now,i have promised my mom to help her with the housework. hope to hear from you soon!
yours,
penpal.
