A student's antics

Saul was a boy with long black hair who loved to play pranks. One day, while wearing his untidy school uniform with a blue sweater and untucked shirt, he had a mischievous idea. He decided to switch all the labels on the classroom computers. Saul giggled to himself, imagining the confusion it would cause. Little did he know, Maestra Carlotta was watching him from the doorway.
