Answer:
Hi mom,
how have you been? my summer vacation has been nice with grandma and grandpa on the farm. Grandpa just bought a new puppy to train to herd sheep and help their current dog. Grandpa also just planted some cherries and grandma said when they were ready, we would pick them and make cherry pies to sell in town, but they won't be ready until the day you come to bring me back home. I was wanting to ask you if I could have money to buy a pair of slippers, a book, and movie tickets. I want slipper because grandpa and grandma's new puppy decided to chew mine up, and you know how dusty the floors are here, especially with a new puppy! I want a new book because the newest book in the series I am reading just came out, along with a movie adaption!
I can't wait to see you,
Love (insert your name here)
Step-by-step explanation:
The letter above is just an example! you can use whatever scenario you want, it doesn't have to be a child going to visit their grandparents for the summer on their families farm. It can be someone going somewhere on a school field trip or to visit their friends back home after moving. And you obviously don't have to make the items slippers, books, and movie tickets, those were just the first things I could think of lol. I hope this helps and you have a great day!
