"Yes." It's a feeble response but you're shocked at being recognized and are somewhat relieved when the van pulls on to Mr Davis's drive and then you remember it being parked there when you set off for the party. "Did, did you follow me?"

"Yes." Said Mr Davis. "You see we didn't like to see how you were treated, and so we thought we would help you get some ****."

"How?" You ask the thought intriguing you.

"She's letting you go to that kids party because she thinks you're a kid how about we have a party at my place that will show her how grown up you are won't it?"

"Yes it will."
