Dear Rosella,
how are you doing? When I got your letter last week I realized we haven‘t talked in month. Thank you so much for including the pictures of your new house and inviting us to visit you in Brazil this summer. I always wanted to go there, but I am afraid we will not be able to make it this summer. Maybe you can visit us instead in Australia? We have just moved to the coast 3 month ago and I have decided to quit my office job. Instead we are now running a small café in a historic beach house. It is quite exciting, but also a lot of work: I get up at 5 a.m. every morning and we usually close after 11 p.m. The house was quite run down when we bought it, but now it looks fantastic. Obviously, I can not close the café for several weeks during summer as we just opened a few weeks ago. We also adopted a puppy named „Spotty“ we can not take on the trip. I attached a few pictures to the letter and I hope they will convince you to come here this summer. Just let me know.
Yours Sincerely,
A. B.
