The girl wasn't quite so sure if he was being serious or not. If he was though, it could have voided the bet, which definitely would have been a good thing for her. Unfortunately, she'd have to actually catch him in the act before she was able to call him out and announce herself the winner. Oh well, she could handle a few more days. He would break soon enough.
This time she couldn't refrain from rolling her eyes though, and she reached down to pull her bag over his shoulder before brushing past him. "Whatever, I won't hold my breath." Alright, she couldn't wait to see what this surprise was, but she wouldn't admit that to him. "I'll see you at lunch, or after school, doesn't matter." And she continued moving, barely making it to her classroom without turning around to give him the middle finger.
[ You can either skip to lunch/after school, or whatever you really wanna do. :3 ]
