Thank you for your letter of October 25. I haven’t written sooner as I were busy preparing for my mid--term exams. We are having a party on 11th November at our house for my sister’s 15th birthday and we hope you can come. It only happens once a year! The party will start at 6 p.m. and will go on until late! I’m at home in the evenings. Please give me a call. We’re looking forward to seeing you.

I am writing to thank you for all the help you gave us in moving into our new flat.

As you know, my mother is in poor health and there is a lot of furniture. I know we would never have been able to move all the things into the new flat without your help.

I am arranging a housewarming party soon and I look forward to seeing you then.

Thank you again for everything you have done for us.

Yours,
