To the cafeteria

Brianna strutted down the hallway. As a senior, she was prepared for the independence that her final year would eventually bring her. But at the moment, she was still bound by the schedule of the school, and right now was her lunch. So she began to make her way to the cafeteria. There, she ordered a sandwich as well as one of her favorite milkshakes and sat down at a table to begin gossiping.

But sometime halfway through the lunch, Brianna felt the need to use the restroom. She quickly got up, leaving her half-drunk milkshake and her empty bag, originally full of sandwich, on the table and left the room. Since she left the cafeteria, leaving her food unattended by alert people, all of her acquaintances paying it now attention, nobody noticed as someone walked by and pulled out a small pouch. The pouch was unlabelled, but the shaking fingers of the person holding the pouch hinted at something very suspicious. The person tore open the pouch, still unnoticed, and in one swoop, dumped all of the contents into the milkshake, watching satisfied as the powder sank beneath the surface of the liquid. They didn't bother to stir it at all, but that wasn't an issue by the time Brianna returned, unaware that anything had occurred. She wasn't paying attention to the teen in the back corner, staring closely at her as she returned to her conversations. She wasn't paying attention to the drink she was holding a few seconds later, her lush lips wrapped around the straw, creating a powerful suction to bring the creamy, delicious drink to her mouth. She wasn't paying attention to the person's expression of near shock and delight as she didn't seem to taste anything different, instead swallowing eagerly. And she certainly wasn't paying attention to anything that the drink might be doing to her.
