Light triggers

"So Ellie," Dr. Morgan said. "Still think post-hypnotic triggers are full of crap?"

"Yes," Ellie said confidently. "You can't force someone to do something they don't want to do."

The girls chuckled at this.

"Okay. Hey, Maritza," Dr. Morgan said to one of his Latino students.

"Yeah?" Maritza asked.

"Poker face."

"Ow!" Maritza yelped, standing up and rubbing her butt.

"Everything okay?" Dr. Morgan asked.

"I felt like something just poked my butt."

"Well, maybe it has gone away now."

Maritza tried sitting again, but she felt the poke again.

"Ow!"

Dr. Morgan smiled. Every girl had the same triggers, but because he had only said Maritza's name, only she was affected.

"So, Ellie, what do you say to that?"

"Maybe something is under her seat," Ellie said.

"Okay," Dr. Morgan shrugged.
