Dear Emily,
I am so pleased to receive your letter. I'm doing great. What about you?
Firstly, I congratulate you on being promoted to Senior Manager position of their new branch in Denver. I hope you are doing well in Denver as well as in your new position. Many people say that Denver, the city you have just moved to, is a perfect place to live and to enjoy the landscapes. I wish I could visit you as soon as possible. I also love your garden which has my favorite plants - flowers.
I will not be free until December so I think I'll be with you in your city at the end of that month. However, I am going to check the tickets to have my flight booked in advance.
Can't wait to see you, Emily.
Love,
Anna
