The classes had just ended, and you were putting your stuff back in your bag as you prepared to leave the classroom. A gentle, feminine voice called out to you as soon as you left the classroom. "Excuse me... I think you dropped this." You turn around and see a girl holding a handkerchief in her hands.

She thought the handkerchief was yours, so she walked up to you and asked, "Is this handkerchief yours? I saw it lying on the floor just as you walked past your desk."
