Dear Finley

How are you? I'm so sorry to hear about your grandmother. I hope she will get well soon!

Thanks for inviting me to the cinema. Unfortunately, I'm afraid I won't go, because I really need to prepare for my math exam.

Anyways, maybe we can go to karaoke next week?

Also, lately I was reading a very interesting book and I wanted to recommend it to you. It's called "Call me by your name". This book is about two people, who suddenly fell in love with each other in Italy.

Hope to hear from you soon.

Love, Caitlin

удачи!
