It Was Just A Friendship Bracelet

Izzy carefully tied the tightest knot she could and squeezed her eyes shut. A moment later, she opened them and smiled. "There. I made my wish. Carry on with your homework."

Julian wasn't about to let her go that easily. He wanted to know what she wished for! No, he needed to know! 

"Izzy, what did you wish for?"

"I can't tell you or it won't come true…or is that birthday cake wishes? Star wishes? It might be wishes in general now that I think about it," she mused. "Sorry. I don't make the rules but I do follow them."

"How am I going to know if your wish came true when this thing eventually falls off then?" he demanded. 

Izzy shrugged. "I guess you're going to have to ask me."
