"Can I make nasty faces at the biker gang down the street?"
Of course you can dear. As soon as your father gets home so he can beat them all up.
Can I have a naked water balloon fight with the kids next door?
Sure, honey, just let me get the camcorder so I can make a video to show your first boyfriend/girlfriend, at your high school prom, and when you get married, and at every birthday party in between.
Can I draw on the walls?
