Dear Riya,

How are you? I hope you're doing well. I am eager to share exciting information about my new school!

I’ve only been for a week, and I’m loving it. The classrooms are big, and the teachers are super friendly. I’ve already made two new friends, Aarav and Zoya. Guess what? We have a big library, and I can borrow two books every week!

I miss the days when we used to go to school together, but I’m sure you would love it here, too. Do write to me about your well-being.

Yours lovingly,

Ananya
