Lost School Jacket Notice
Attention all students:
This is to inform you that I have lost my school jacket. It's possible that I misplaced it in the school cafeteria or library yesterday. The jacket is dark blue with the school emblem on the chest. If anyone has found it or has any information about its whereabouts, kindly contact me directly or hand it over to the lost and found section of the administration office.
I am offering a small reward to the person who returns it. Your help is greatly appreciated, as the jacket holds sentimental value to me. Please help spread the word.
Thank you for your cooperation.
