Answer:
To my dear friend,
I am thrilled to tell you that I have won a scholarship to study abroad! While this is a very exciting opportunity, this will also be a very hard step for me to take. I am going to miss my family and friends terribly. I know I may always call or text them, but I'm so sad I won't be able to see them face to face. I will also miss my dog, Mr. Lady. Unfortunately, I'm unable to take him on this journey with me. But thank you so much for promising to care for him while I'm away! I'm sure the two of you will get along wonderfully. Please give Mr. Lady lot's of belly rubs for me! I must go pack my things now, but I'll write to you again soon.
Sincerely, your best friend
