Answer:
Dear Brother,
The family and I are very excited about your arrival next Saturday. We can't wait to see you again after three years abroad. As we are happy to see you again, we are preparing everything for your arrival.
First of all, we are organizing a big welcome party. We have already invited your school friends, ex-coworkers and relatives and your friends from the football club. There will be a lot of food and even a Dj.
Dad and I are cleaning and fixing things in your room. We have already vacuumed, and we are now taking all the things that we have storage in your room while you weren't present. While we are fixing your bedroom, mom is buying and cooking all the things that you like. She bought all the ingredients to bake you a chocolate cake!.
As you can see, we are counting the minutes to see you again and hug you. Have a safe flight and see you soon.
All the best,
Susan.
Explanation:
When we write a letter to a friend or a relative, we have to use informal language. Also, we divide the letter into three main sections.
First, we write the introduction. In this section, we address our brother and tell him that we are excited about his arrival. Secondly, we have the body of the letter. In this part, which can have multiple paragraphs, we describe all the different things that we are doing for his arrival. Lastly, we write a closing paragraph telling him how happy we are to see him again and say our goodbyes.
