Answer:
Put it into translate.
Step-by-step explanation:
Just start it off as this.
Dear (Name),
I hope you are well. I had such a great week! I did (something fun!) and I played with (Family Member.) I had such a great time playing with (Family member) at (Fun place.)
That can be the first paragraph.
Then you continue asking about them and how they are doing. You can also make up something bad going on with one of their Family members and write a whole paragraph on that. I hope this helps!
