Dear ...,
Thank you for your letter. It was great to hear from you.
I am sorry that you are very busy, you should rest and that is why I
think it would be nice to go to the football match. I am glad that you
think so and I also shall be happy to see you.
Yes, I am a football fan and I think it's one of the most exciting games. It is so interesting to watch football matches.
Honestly, I don't know how much the tickets are, but my friend said it costs 200 rub.
Sorry, I have to go. My mum is calling me. I'm looking forward to seeing you too!
Best wishes,
