1. In your last letter, you kindly offered to put me up your flat when I was in Berlin.

2. I am afraid that I am unable to take the offer at that time being.

3. My father is sick so I have to stay at home to take care of him.

4. He is very sick so I can not let him alone.

5. My brother also helps to look after my Dad but he is away now for his business trip to Paris.

6. I hope I will be able to come to Berlin later at the end of year, perhaps in January.

7. If my room is free I will be very glad to stay with you.

8. I will let you know my plan as soon as possible in order not to interfere your own plan.

9. Thank you very much again for your offer.

10. I can not wait to see you in Berlin but then goodbye.
