The boy was laughing at your classmate, Lilian. You approached Lilian, asking about the boy, and she said she didn't know him.

Lilian was getting angry by the boy laughing at her, so you asked him about it.

He said that the cap of the camera Lilian was taking pictures with was on, which meant it was no use for her to take so many photos, her films in waste.

Lilian and you soon left the place after Lilian gave you your camera back. It was your camera. You left to get sandwiches and she took photos, with the cap on, your film in waste.

You sat down on the bench, and not any later, the same boy came and sat down beside you, but keeping a good distance.

"I suspected it was your camera, given the fact that your friend didn't even know that the camera has a cap." He starts, causing you to look up at him.

He smiles at your tiredness and holds out a film.

"Here, I bought it for you." Says the boy you just met.
