- My name is Rhythm and I am a student of class X A of this school.
- Yesterday, while commuting by the school bus, I lost my pencil box that also had my library card.
- I tried to look for it, but could not find the same.
- I request you to issue a duplicate library card so that I can still borrow reference books for studying for the Board exams.
- I would be thankful to you.

Regards
