You help her with the address.

Seeing the pink piece of paper in her hand, wet from the rain, you ask, "Can I see that flyer."

She hands it to you and states, "Sure, but aparently this has the wrong address."

"Yup as I thought, this happens sometimes, you see that isn't my address, that is for east 39th street, and you are on west 39th street."

"So you know where this is?" she asks with a wry grin.

"Yeah it's just across town, It isn't all that far, I could give you directions."

"Thanks, Heck would you like to come with me, the prize for best costume is $1000, and the booze is free."

"Sounds like fun but I don't have a costume."

"No problem I know of a little place not far from here that should still be open."

Hmm hang out with a hot chick at a party or stay here, as if there was even a doubt. "Sure, what the hell lets go." You state with a smile. Then you hop in her car and she speeds away. As you arrive they are locking up. "Wait please I need a cool costume to win a contest at a party I will give you 100 bucks to use it for the night."

The shopkeeper looks you over and says, "Ok I guess but I know I only have one costume left that would fit you." With that he goes back in and returns handing you one of those long bags like you get a suit in on a hanger. You pay him and he locks the door and leaves. Not having anywhere else to change considering your small car you duck around back and change behind the dumpster.
