1. I've read your letter and i've thought about your idea. I iike it very much. Lets Talk about this!
2. It would be amazing if you and your family come to me in the holidays. We'll have a good time together!
3. You wrote that you are going to fly on a plane on 28 december. I know when the plane arrives, I'll meet you in airport at 10 am.
After airport we'll take a breakfast in the cafe. After this we'll go to my house and you'll relax after heavy road.
4. I think we're gonna (going to) do. We can go to the museum, or cinema, or walk in the park. You offered tour (не совсем поняла, что за экскурсия по народу, не знаю как сказать)). That's a great idea.
I wish meet you soon!
5. Goodbye!
