Dear Helen,

I hope you are all right and that you are happy to live in your new flat. Thanks for the invitation to your housewarming party but I am in Estonia with my family now.

We have been here since 1st July and we are coming back to Moscow only on 31st August. We are staying with our friends Martha and Hannes who live in the centre of Tallinn. Their flat is in a very pleasant area near the sea. They have had this flat for two years. It is very attractive and spacious.

I have known Martha and Hannes for a year but I have such a feeling that I have known them all my life. They are very good friends.

Since our arrival we have travelled a lot around Estonia and have enjoyed picturesque views. Tomorrow we are going to Narva to see an old fortress.

I regret to miss your housewarming party but I promise to visit you as soon as we come back.
