Perfect betrayal

[Katherine Grillet]

Katherine lowered her head towards her friend while Andrew looked interested at some smiling paper and whispered.
"Are you flirting with him?!"
Kennya looked in disbelief at her companion and she stuck her tongue at her.
"Yep, you are not the type to flirt with a muggle." Kath winked.
Andrew, feeling slightly embarrassed, was silent for a few moments. He only stayed silent until the hum and buzz of the store drove him into a leg-bouncing, finger-tapping, eye-shifting madness.

"So…"
"You just can't stay quiet, can you?" Katherine stretched out in the chair behind the counter, her joints popping as she did so.
"Did you want me to?"
"Nah," Kath smiled.
"Okay, because I can't really stay quiet," the boy laughed.
"I figured that from the moment you opened your mouth." the slytherin said sincere.
