Write a letter to your friend for borrowing a book from him

Hey there Saikat,

I hope you're doing well. I'm good too. I have a little favor to ask. Would you mind lending me your "English For Today" book? I lost mine last week, and I really need it for about a week. You see, our exams are coming up in just 15 days, and I've got 10 days left to study all the subjects. So having that book would be a huge help.

If you can lend me the book, I'd really appreciate it. It would make a big difference for my exam results. I've already covered all the subjects except English.

That's all for now. Say hi to your parents for me, and send some love to your younger siblings.

Take care,

Sawon
